The FLINT oscillator is based on Yb:KGW crystal end-pumping by high brightness laser diode module. Generation of femtosecond pulses is provided by Kerr lens mode-locking, once started, modelocking remains stable over a long period of time and is immune to minor mechanical impact. The oscillator can be equipped with external electrooptical Pulse Picker and appropriate timing electronics allowing selection of a single pulse at repetition rates up to 100 kHz. Piezo-actuator can be implemented in customized oscillators in order to control the cavity length. FLINT oscillator can also be equipped with Carrier Envelope Phase (CEP) stabilization system.
LOCKING OF THE OPTICAL PULSE TO AN EXTERNAL SIGNAL
Pharos oscillator can be equipped with piezo actuators for precise control of the cavity length.
CARRIER ENVELOPE PHASE (CEP) STABILIZATION
Pharos oscillator can be equipped with nonlinear interferometer and feedback loop throughout the pump current of the laser diode bar for CEP stabilization. The figure on the right shows typical measurement of power spectrum density and integrated CEP phase error. The integrated phase error is in the frequency range from 50 Hz to 10 MHz is <70 mrad (in loop measurement).
