Research output: Patent


A voltage-controllable output coupler for a laser, comprising: a liquid crystal cell that provides a change in birefringence in response to an applied voltage; and a polariser oriented with respect to the liquid crystal cell to collectively form a variable reflectance mirror for the laser; wherein output coupling of the laser is controllable by applying voltage to the liquid crystal cell for a switching interval to switch the variable reflectance mirror from high reflectance to low reflectance, and vice versa, thus actively Q-switching or cavity dumping the laser.
