ABSTRACT:
A wedge mirror is disclosed for suppressing the high gain wavelengths in a laser. The mirror is provided with a pair of opposed surfaces lying in nonparallel planes. Each of the surfaces is provided with a wavelength selective coating. The coating on the surface of the mirror facing the gain medium is highly reflective of the high gain wavelength and highly transmissive of the low gain wavelength. This surface is oriented so that the light from the high gain wavelength is reflected out of the cavity. The outer surface of the mirror is highly transmissive of the high gain wavelength and highly reflective of the low gain wavelength. The combination of the wavelength selective coatings and the wedge configuration allows the high gain wavelength to be suppressed while the low gain wavelength oscillates. The subject mirror is particularly suited for suppressing the 1.06 and 1.33 micron wavelengths in Nd:YAG while allowing the 1.44 micron wavelength to lase.
