Abstract
A single longitudinal-mode laser includes a first mirror and a second mirror that define a laser cavity therein that does not include a linear polarizer. A birefringent gain medium can generate a lasing light at a lasing wavelength along a light propagation direction in response to a pump light at a pumping wavelength. The birefringent gain medium has an optical axis substantially perpendicular to the light propagation direction. A first wave plate positioned between the first mirror and the birefringent gain medium is a quarter wave plate at the lasing wavelength and a whole wave plate at the pumping wavelength. A second wave plate is positioned between the birefringent gain medium and the second mirror. The first wave plat and the second wave plate in part produce a single longitudinal mode in the lasing light.
