Abstract
A method of Q-switching a laser utilizing a waveguide with a strongly localised guiding region is disclosed. A laser cavity including an input pump beam, a highly reflective mirror, a waveguide gain medium, a collimating material, an electro-optic device, and an output coupler is disclosed. The electro-optic device may be an electro-optic deflector or an electro-optic scrambler. Various electro-optic deflector and scrambler geometries are disclosed which allow for Q-switching a laser. The collimating material may include one or more lenses or may instead include a metamaterial layer for appropriately collimating the input pump beam.
