Industrial Lasers Industrial Lasers High-Power Femtosecond Lasers FEATURES Single pulse – 1 MHz tunable repetition rate Includes pulse picker for pulse-on-demand operation Rugged, industrial grade mechanical design PHAROS is built upon the conventional chirped pulse amplifi­ cation technique, employing the seed oscillator, regenerative amplifier and pulse stretcher/compressor modules. A Kerr lens mode-locked oscillator delivers >700 mW output with sub-80 fs pulse duration. The regenerative amplifier is based on Yb:KGW lasing medium. Both oscillator and amplifier are non-collinearly pumped...
