SL 300 series lasers are an excellent solution for applications that require high energy picosecond pulses. Pulse compression during backward?stimulated Brillouin scattering (SBS), used in EKSPLA SL300 series lasers, is a simple and cost?efficient way to generate picosecond pulses, with the unique capability of producing pulses with tunable duration.
An electro-optically Q-switched Single Longitudinal Mode (SLM) nanosecond generator is the heart of the system. Instead of external narrow linewidth diode lasers, the selective properties of Fabry-Perrot etalon, and a laser cavity are used to produce SLM pulses with a smooth temporal envelope. In scientific literature this method of generating SLM pulses is known as a selfseeding technique.
Pulse compression is done in a SBS?cell. Depending on the geometry of interaction, a pulse with duration in the 170 – 1500 ps range can be produced. Pulse duration can be tuned in discrete steps when a variable pulse duration option (-VPx) is installed.
After SBS compression, the pulse is directed to a multi-pass poweramplifier system for amplification to up to 500 mJ energy. Temperature controlled 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.
A power supply and cooling units are placed in a standard 19" rack that requires little space under an optical table.The very low jitter of the optical pulse relative to the Q-switch triggering pulse ensures reliable synchronization of the laser with external equipment. For customer convenience the laser can be controlled from a user-friendly remote control pad or RS232 interface. The remote pad allows easy control of all laser parameters and features a backlit display that is easy to read even when wearing laser safety eyewear.
Alternatively, the laser can be controlled from a personal computer with supplied software for a Windows™ operating system. LabView™ drivers are supplied as well.
