STKM Series Femto-second Lasers (EUV to IR)

1. STKM-YFi High Power and Repetition Rate Near-IR Ultrafast Fiber Lasers

The STKM-YFi laser series is a family of high average power, high repetition rate near-IR ultrafast fiber lasers. STKM-YFi products are based on a single rugged opto-mechanical platform and are engineered for hands-free operation.

STKM-YFi Outstanding Characteristics

The STKM-YFi system employs a patented all normal dispersion (ANDi) mode-locked fiber laser coupled with a fiber amplifier. This configuration offers numerous unique advantages, including:

• Bandwidth supporting sub-100 fs pulses
• High output energy from oscillator requires less amplification for shorter, low temporal pedestal pulses
• Robust long-term operation

The short, clean pulses of the STKM-YFi laser series deliver more peak intensity per mJ than competing products. We guarantees both pulse duration and pedestal energy content, verified with a FROG pulse measurement, to ensure each laser pulse is free of picosecond background that robs energy from the main short pulse. Thus, more of the laser output is truly usable, requiring less energy/average power and decreasing the probability of seeing collateral damage and other detrimental interactions.

Features:

• Average power: 5W / 20 W / 50 W (STKM-YFi / STKM-YFi HP / STKM-YFi Ultra)
• < 150/170/190 fs pulse length with low pulse pedestal gives improved performance for driving nonlinear optical interaction: optimum efficiency at lower pulse energy / average power
• Tuneable repetition rate (0.5-15, 60MHz)
• Fully integrated, ruggedized, hands-free laser source
• Stable over large temperature range (16-26˚ C)
• Graphical, intuitive software control with integrated diagnostics
• Computer controlled pulse width pre-compensation: optimize your experiment with no external prisms or gratings

2. STKM-XUUS-5 High Harmonic Generation Source for EUV and Soft X-ray (10nm to 50nm)

Coherent, EUV-wavelength light, made through high harmonic generation (HHG), has finally come of age. STKM-XUUS-5 is our fifth generation of EUV conversion platform designed to offer “black-box” conversion of ultra-short, infrared laser pulses into short wavelength, laser-like radiation. Our patented use of fiber-based HHG architecture ensures repeatable, highly-stable, bright and low gas-usage generation of EUV light.

STKM-XUUS-5 upconverts ultrafast laser pulses into the Extreme UV (EUV or XUV) or soft X-ray regions of the spectrum. Employing HHG processes, the output beam inherits the coherent properties of a driving laser such as the amplifier with wavelengths that can be tuned from ~10 to 50 nm. Moreover, customized systems can generate coherent beams with wavelengths as short as 6 nm. The STKM-XUUS-5 employs our patented hollow waveguide for the high harmonic up-conversion process.

The STKM-XUUS hollow-core fiber, or waveguide, architecture enables harmonics generated by the system to be distinguished from other HHG methods, guaranteeing your harmonics originate from the same point in space every time, minimizing any pointing drift. This architecture optimizes repeatability for your experiments. Additionally, the use of a fiber--rather than typical gas jet or semi-infinite gas cell target geometries--provides superior pressure tunability for phase-matched HHG. Now you can choose robustness without sacrificing flexibility.

3. STKM-Hyperion-VUV – Vacuum Ultraviolet Source (115nm to 205nm)

We provide bright femtosecond pulses at numerous wavelengths across the vacuum ultraviolet (VUV) region, from 6.0 eV (205 nm) to 10.8 eV (115 nm). The discrete tunability of the our STKM-Hyperion-VUV vacuum ultraviolet source enables researchers to study a wide range of materials and materials properties. A simple computer-selected change of photon energy provides a powerful capability, previously only available at a synchrotron; this ability to easily change the laser wavelength can enhance many experiments. For example, in angle-resolved photoemission (ARPES) experiments, this tunability allows researchers to distinguish surface effects from bulk effects. For time-of-flight (ToF) studies of molecules, the tunability can distinguish otherwise identical isomers.

STKM-Hyperion-VUV is also highly focusable, and the appropriate optics can be used to reach spot sizes below 10 microns. This ability will allow researchers to examine new types of samples, including materials that are polycrystalline, spatially inhomogeneous, faceted, or simply very small.

STKM-Hyperion-VUV produces pulses with durations below 250 femtoseconds, enabling scientists to probe ultrafast dynamics of molecules and materials. The 1 MHz repetition rate enables rapid data collection and avoids space-charge effects.

Additionally, STKM-Hyperion-VUV is “application ready,” including the appropriate focusing and beam-steering elements to enable fast integration with experimental apparatus.  Importantly, STKM-Hyperion-VUV can be used with a window between the source and the experimental chamber, guaranteeing that applications demanding ultrahigh vacuum (such as ARPES) will remain contamination-free.

In addition to ARPES, STKM-Hyperion-VUV will enable breakthrough research in photoemission electron microscopy (PEEM), photoionization mass spectroscopy (PIMS) for combustion research, and other studies of next-generation materials and molecular systems.

STKM-Hyperion-VUV:

• Is discretely tunable
• Provides high energy resolution
• Enables femtosecond time-resolved experiments
• Allows high spatial resolution
• Provides synchrotron-quality VUV in your lab

Applications:

• Angle-resolved photoemission spectroscopy (ARPES)
• Time-resolved ARPES
• Photoemission electron microscopy (PEEM)
• Photo-ionization mass spectroscopy (PIMS)
• Molecular time-of-flight (ToF) studies
• Applications that require tunable VUV light
• Applications that require femtosecond pulses of VUV light

Features that lead to significant benefits:

Tunable (computer-selected) photon energy between 6–10.8 eV enhances capabilities for laser ARPES experiments:

• Achieve high momentum resolution using low energy photons (< 7 eV) and still cover higher momentum range using higher energy photons (> 10 eV)
• Obtain surface vs. bulk information
• Reveal "hidden bands" by changing wavelength
• Bandwidth is adjustable to optimize data collection

Tight focal spot provides greater sample flexibility, allowing the study of

• Extremely small samples
• Spatially heterogeneous samples
• Polycrystalline materials

A window provides complete isolation between Hyperion VUV and the experimental chamber, maintaining high vacuum

Femtosecond pulses enable time-resolved experiments
