Ekspla SL330 Series SBS Compressed Picosecond Nd:YAG Lasers

Picosecond SBS compressed high energy NdYAG lasers SL330 series 2

Ekspla's SL300 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 power amplifier 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. Read more
