3.4 STLB-GR Series Q-Switched Nd:YAG Laser

STLB-GR Series Super-Gaussian Resonator series Q-Switched Nd:YAG lasers combine VRM (variable reflectivity mirror) with unstable resonator design creating a cavity with large TEM00 mode volume for excitation and energy extraction. A “flat-top-hat” can be specified with uniform energy distribution or “VRM Gaussian” profiles.

STGR Series close-coupled diffuse pump chamber delivers uniform pumping of the laser rod for optimum lasing excitation efficiency and allows for higher stored energy by eliminating parasitic oscillations within the pump chamber. The pump chamber uses chemically inert materials to withstand high pumping energy and absorb unwanted UV and IR radiation emitted by the flash lamps. One or more amplifiers can be added to the oscillator for higher energy output. With scientific or industrial grade models available, the STGR series will fit right in with your scientific research, medical or OEM industrial application.

4. STLQ Series EO Q-switched Lasers

4.1 Compact Air-cooled Nd:YAG Laser Model STLQ115

Up to 90mJ @ 1064nm and built in harmonic generators 532nm, 355nm, 266nm

FEATURES:

The STLQ115 is an ultra-compact model of air-cooled Nd:YAG laser for applications requiring compact and undemanding laser source.

Due to application of original high-efficiency heat exchanger the STLQ115 laser unlike most air-cooled laser models can work continuously with PRR up to 3Hz and cyclically with PRR up to 5Hz. The above operating modes are realised at output energies conventionally attained at water-cooled lasers.

The STLQ115 laser provides up to 90mJ output pulse energy at the fundamental with possibility of further conversion of IR radiation into the second harmonic as well as into the third or fourth harmonic.

All the harmonic generators are built-in and temperature stabilised. This peculiarity together with optimised rigid laser head design ensures output radiation long-term stability comparable to that of standard laboratory lasers.

Unlike most compact lasers using DKDP-based Pockels cells, the STLQ115 incorporates LiNbO3 electrooptical Q-Switch. Such Q-Switch is not hygroscopic and retains its parameters within a wide temperature range and ensures reliable and stable laser operation.

Dust-proof laser head design allows to align main optical components without removing the cover that increases their life in the field.

To reduce your time expenses on routine service of the STLQ115 laser we use only long lifetime flash lamps by Heraeus Noblelight Ltd. Besides, the flash lamp replacement procedure is elementarily easy even for a unskilled user.

Absence of water cooling system gives to the STLQ115 laser a number of essential operational advantages:

4.2 Compact Nd:YAG Laser Model STLQ​215

Up to 180mJ @ 1064nm and harmonic generators up to 213nm

FEATURES:

The STLQ215 laser is built on the basis of a model produced for aerospace industry and combines excellent beam quality required for advanced scientific research with a highest reliability of industrial equipment.

Original and reliable optical scheme ensures compensation of both astigmatism and thermooptical distortions and places at your disposal laser radiation of the highest quality.

One more peculiarity of the laser optical scheme is that all the components operate at loads considerably lower than the admissible values. Such a smooth operation mode not only increases life time of the components but also ensures unique operational reliability of the whole laser. As a result, you can use the

STLQ215 laser for your experiments day-to-day and year-to-year having forgotten about repairs and other unpleasant operation costs.

All the laser optical components are installed on a rigid base fixed to the housing with specially developed dampers. Due to this, mechanical vibrations and housing stress no way influence the quality of the cavity alignment.

All the critical components of the laser are thermally stabilised which in combination with vibration-proof design ensures unsurpassed long-term output radiation stability. The efficient thermostats used in the STLQ215 ensure warm-up time of less than 10min.

To reduce your time expenses on routine service of the STLQ215 we provided flash lamp life time of more than 50 million pulses and foreseen easy and quick procedure of its replacement.

It should be noted that the laser design allows to replace the flash lamp without removing the laser head upper cover. Such a technical solution considerably reduces risks of the optical components contamination as well as increases operational reliability of the device.

Closed-loop water-to-air cooling system is integrated into a compact single-phase laser power supply which can be controlled both from PC and via the remote control unit.

If you plan to use the STLQ215 in laboratory experiments, as a bonus you will get unsurpassed operational reliability and minimization of accompanying expenses.

If you are attracted by the reliability of the STLQ215 laser and you will use it for industrial or field applications, in addition to a highest reliability you get beam quality conventionally available only for high-precision laboratory equipment.

The STLQ215 is an ideal instrument for such applications as:

4.3 Dual-Pulse Compact Nd:YAG Laser Model STLQ215-D

Up to 100mJ @ 1064nm and 50mJ @ 532nm in each pulse

FEATURES

The STLQ215-D is built on the basis of a laser produced for aerospace industry and combines excellent beam quality required for advanced scientific research and a highest reliability of industrial equipment.

The design of conventional lasers generating dual pulse is based either on combining two lasers or on successive generation of nanosecond pulses by one active element during one flash lamp discharge pulse.

The first solution allows to build a system with the maximum capabilities for the user but leads to increase of its cost and dimensions. The second approach allows to create low-cost and compact systems but leads to reduction of each pulse energy and of laser beam profile worsening and stability as well as limits the delay range between the pulses.

The STLQ215-D design demonstrates advantages of both the variants but eliminates their disadvantages: output radiation is generated by two separate cavities while both the Nd:YAG rods are installed in one pump chamber and are pumped by one flash lamp. Both the cavities are integrated into a common laser head controlled by a common power supply that provides to the user minimum dimensions and convenience in controlling dual pulse parameters.

Original and reliable optical scheme ensures compensation of both astigmatism and thermooptical distortions and places at your disposal laser radiation of the highest quality.

One more peculiarity of the laser optical scheme is that all the components operate at loads considerably lower than the admissible values. Such a smooth operation mode not only increases life time of the components but also ensures unique operational reliability of the whole laser. As a result, you can use the STLQ215-D laser for your experiments day-to-day and year-to-year having forgotten about repairs and other unpleasant operation costs.

Up to 500mJ at 1064nm and harmonic generators up to 213nm

FEATURES:

The STLQ529 is a series of popular compact lamp-pumped Nd:YAG lasers offering uncompromising combination of the main parameters: high output power, exceptional beam quality and minimum laser head and power supply dimensions.

All the lasers of the STLQ529 series are based on ring cavity and incorporate a pump chamber with diffuse ceramic reflector. Due to this technical solution the STLQ529 lasers, unlike the lasers with traditional linear cavity, provide homogeneous close to flat-top laser beam profile and possess exceptional stability of output energy and spatial radiation parameters.

Up to 200mJ @ 1064nm and harmonic generators up to 213nm

FEATURES:

The combination of high laser pulse energy, high PRR and excellent beam quality unattainable for most conventional models is the peculiarity of the STLQ629 laser.

Active elements of master oscillator and amplifier are installed in one pump chamber and are pumped by a single flash lamp.

Particularly due to this technical solution the STLQ629 provides unique combination of parameters in a compact, reliable and inexpensive-in-operation design.

All the critical components of the laser are thermally stabilised which in combination with vibration-proof design ensures unsurpassed long-term stability of output radiation. The efficient thermostats used in the STLQ629 ensure warm-up time of less than 10min.

To reduce your time expenses on routine service of the STLQ629 we provided flash lamp life time of more than 50 million pulses and foreseen easy and quick procedure of its replacement.
