Piezo-actuator can be implemented in customized oscillators in order to control the cavity length. FLINT oscillator can also be equipped with a Carrier Envelope Phase (CEP) stabilization system. The FLINT oscillator is based on Yb crystal pumped by a high brightness laser diode module. Generation of femtosecond pulses is provided by Kerr lens mode-locking. Once started, mode-locking remains stable over a long period of time and Pulse duration (assuming Gaussian pulse shape) Model Max. average power Repetition rate Centre wavelength Output pulse-to-pulse stability Linear, horizontal Beam quality Beam pointing stability Internal attenuator PHYSICAL DIMENSIONS Laser head Power supply and chiller rack Included.
