1. Compact AO Q-switched DPSS Lasers – SOL Series

SOL is the most compact Q-switched diode pumped solid state laser available in the power range from 6W to 40W @1064nm. Sol versions at 532nn are also available with the same footprint. These air-cooled DPSS lasers are offered in a rugged and lightweight single unit, designed to allow easy and reliable integration in micro-machining and marking applications.

The Sol single unit design is based on a permanently aligned monolithic optical resonator integrated with 24VDC powered driving electronics. Cooling of the unit is provided by low noise fans. Due to the single unit design, optical fibers and other delicate cable connections will not be necessary for system integration. Compactness, insensitivity to environmental conditions and ease of handling guarantee superior operation flexibility and performance/cost ratio.

The high peak power and the excellent beam quality of Sol lasers make them the ideal source for the most demanding industrial and scientific applications.

7. NPS-Narrowband ps Lasers

Our Nps laser platform is a new ultrafast picosecond laser series, especially tailored for spectroscopic applications, by combining compactness and ruggedness of fiber laser technology with spectral purity of the DPSS design.

According to the number and the features of the proprietary amplification stages, it is possible to achieve several power levels at 1064.3nm and its harmonics. The new ultrafast Nps-1064-10 laser operates in the regime of few picoseconds pulse durations (7ps) with average power of 10mW at a repetition rate of 40MHz. The transform-limited operation (spectral width < 0.3nm) and remarkably accurate central wavelength (1064.3±0.1nm) make this laser a suitable candidate for highly efficient amplification by Nd-doped DPSS amplifiers, opening the way to applications in non linear optics (i.e. OPO pumping) and narrowband Raman spectroscopy.
