Abstract
We present a nonlinear-mirror (NLM) mode-locked crystal waveguide laser. By adding nonlinear crystals into traditional NLM devices, the fourth harmonic is generated to form loss modulation, which suppresses the Q-switching instability of mode-locked lasers and achieves the optimal equivalent transmittance. The NLM mode-locked laser delivers ∼30 W average power with a repetition rate of 32.2 MHz and a pulse width of 950 fs. It is revealed that this novel, to the best of our knowledge, design with simple, robust, and reliable structure has a great potential in the development of high-power mode-locked laser.
