Abstract
A laser assembly includes a semiconductor diode laser having an exit facet and capable of emitting a beam at a selected wavelength from the exit facet, a fast axis collimator optically coupled to the exit facet, the fast axis collimator for receiving the beam emittable from the exit facet and for collimating the beam along the fast axis thereof, and the fast axis collimator has one or more exterior surfaces, such that at least one of the one or more exterior surfaces includes a coating that is highly reflective for reflecting light at wavelengths other than the selected wavelength and anti-reflective for transmitting light at the selected wavelength.
