ABSTRACT:
An interchangeable insertable diode laser and lens frame is described in which a pair of lenses is disposed in the frame with a diode laser disposed between the lenses. The laser light from one of the facets is collimated by one of the lenses, such that when the frame is inserted into a housing and coupled to an external cavity in which a diffraction grating is disposed, the grating disperses the light and dispersed light is focused on the facet causing the diode laser to generate single frequency radiation.
