355nm 140 kHz Passively Q-Switched Nd:YAG lasers

A PQS microchip laser is the seed of PicoFlash™ and sets the short pulse width while the fiber amplifier provides the gain, compactly and efficiently. This Master Oscillator Fiber Amplifier (MOFA) architecture enables a constant pulse width, while allowing the user to vary the pulse energy (or peak power). The output is free-space coupled, preserving peak power and beam quality.

The third harmonic conversion stage of the PicoFlash™ series delivers UV light with a Gaussian like beam which enables tight focusing an high power densities.
