High Q Laser has launched the ultra compact Femtoregen UC – an all-in-one femtosecond regenerative amplifier - delivering 2W power at 200kHz repetition rate with 350fs pulse duration on a footprint of 34 x 78cm.


The system presents industrial reliability and robustness and can be customised to an OEM integrator's needs for medical, industrial and scientific applications such as tissue engineering and nano processing.

The all-in-one regenerative amplifier system Femtoregen UC (Ultra Compact) is based on the high end Yb-doped laser materials for future power and repetition rate scaling. It utilises High Q Laser's patent pending Intra-Cavity-Chirped-Pulse-Amplification (ICCPA) for ultra compact design.

The Femtoregen UC integrates all pump laser diode modules, the seed oscillator and the amplifier in a single ultra compact housing. The seed laser is designed as a High Q Laser ultra compact (UC) module itself for high stability and compactness. The UC seed oscillator is operating with de-rated nominal pump current for longest MTBF and is based on High Q Laser’s patented resonator folding technique withstanding a 50g shock test for most robust performance. The semiconductor saturable absorber mirror (SESAM) assures passive and self-starting mode locking for high temporal stability.

The Femtoregen UC comprises the resonator of the regenerative amplifier and the Pockels cell in one monolithic module, the proven High Q Laser IC (Industrial Compatible) module. The Pockels cell and its electric driver modules can both be independently replaced for an easy service in the field.

The device features a single 19-inch unit all-in-one-electronics, hosting all supply and control functions for easy and true 'turn-key' operation and facilitates system integration for OEM customers with a CAN bus and 24V power supply.
