Abstract

See full text

An external cavity diode laser system includes a thin film filter. The output facet of the laser diode is coated with a partial reflection coating and the cavity side facet is coated with an anti-reflection coating. A roof-top prism or corner cube retroreflector serves as the laser cavity end reflector and provides stability of the wavelength of the output over time. The laser cavity lies between the partial reflective coated facet of the laser diode and retroreflector. A collimating lens and a thin film filter are located between the end reflector and the laser diode cavity side facet. The lasing wavelength can be adjusted during either manufacture or operation by tilting the filter. Also included is thermal compensation in the mounting for the retroreflector to compensate for thermal movement of the laser system cavity.
