Features

  • Sub‑40 fs without any additional pulse compressor
  • 250 nJ pulse energy
  • 20 W output power
  • 76 MHz is standard

Overview

The FLINT oscillator is based on Yb crystal pumped by 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 is immune to minor mechanical impact. 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.
