PicoSpark™: the new multiwatt laser by Teem Photonics

 

Technical Specifications:

The PQS microchip laser is the seed of PicoSpark™ and sets the pulse width in the hundreds of picoseconds; at the microchip laser output is coupled into a fiber amplifier, which serves as the gain stage.

This Master Oscillator Fiber Amplifier (MOFA) architecture allows the pulse width to stay constant, while allowing the user to vary the pulse energy (or Peak Power) and the repetition rate independently of each other.

PicoSpark™ produces pulses with energies of hundreds of MicroJoules at repetition rates of a few tens of kilohertz, so average powers of several Watts. PicoSpark™ is housed in a compact, turnkey package, with an output collimated in free space.
