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 freespace 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.
