The Tristar incorporates reliable technologies from field-proven Spectra-Physics diode-pumped solid state (DPSS) lasers and is designed to produce >3 W of power at 50 kHz repetition rate. It is an excellent choice for demanding applications where highly focused spots, precision positioning, and the highest possible throughput are necessary. With a pulse width <25 ns at 90 kHz, the Tristar laser generates the high-intensity peak power necessary for next-generation scribing applications. The high peak power also provides the best quality materials processing and increased throughput. The Tristar laser offers: • Compact, easy to integrate design. • Short pulse durations for smaller heat affected zones. • High peak power reduces recast material, lowers kerf heights and results in cleaner scribe lines and more consistent material processing. • Lower cost of ownership. • Longer life ProLite® diode pump modules for higher reliability. • EternAlign™ optical mount technology for perfect alignment over the lifetime of the laser. • Automatic crystal shifter extends lifetime and lowers the cost of ownership over the life of the laser. • Unique Active Laser Purification System™ keeps the cavity clean and dry to significantly extend laser life. 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 0 50 100 150 200 250 Repetition Rate (kHz) Power (W) Tristar 355-3 Tristar 355-1
