SL200 series lasers are an excellent solution for applications where high energy picosecond pulses are needed. Unlike conventional mode-locked lasers that typically use saturable nonlinear absorption or Kerr lensing to produce ultrafast pulses, the SL200 series lasers employ backward stimulated Brillouin scattering (SBS) in liquid for the same purpose.

Innovative design

A diode pumped electro-optically Q-switched single longitudinal mode (SLM) nanosecond generator is the heart of the system. It provides a nanosecond optical pulse that is later compressed during SBS in a special cell. Since the master oscillator is Q-switched, it allows precise external triggering with jitter of less than 0.2 ns rms. Mode-locked lasers typically have jitters of at least tens of nanoseconds or worse. Precise sync pulses from an internal delay generator are also available with less than 100 ps rms jitter relative to optical pulse.
Pulse compression is done in a SBS-cell with CCl4 liquid. The geometry of interaction is designed to produce the shortest and most stable pulses of 100 ps duration.
After SBS compression, the pulse is directed to a multi-pass flashlamp pumped power amplifier for amplification up to 250 mJ pulse energy.
Thermocontrolled harmonics generators, based on angle-tuned KD*P and KDP crystals and harmonic separation optics are available as standard options. Each wavelength has a separate output port.
Built-in energy monitors continuously monitor output pulse energy. Data from the energy monitor can be seen on the remote keypad or PC screen.
Power supply and water/water type cooling units are mounted in a standard 19” rack.

Simple and convenient laser control.

The laser is controlled from a supplied netbook PC via a USB port with application for Windows™ operating system.
In addition, the laser's major settings can be controlled from an auxiliary user-friendly remote control pad.  The remote pad features a backlit display that is easy to read even while wearing laser safety eyewear.
