1064nm & 532nm Passively Q-Switched Nd:YAG lasers:  high irradiance, multiwatt

PicoSpark™ brings together Passively Q-Switched (PQS) microchip laser technology with fiber amplification, resulting in a multiwatt laser that generates pulses with hundreds of kilowatt peak power and hundreds of gigawatt per square centimeter irradiance.

A PQS microchip laser is the seed of PicoSpark™ and sets the pulse width in the hundreds of picoseconds; a 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) and the repetition rate independently of each other.  The output is free-space coupled, preserving peak power and beam quality.

The Picospark™ HNP series emits 5.5W at 1064nm; the HNG series emits 3.5W at 532nm, generated by harmonic conversion, both with an M2 of 1.4 or lower.
