ABSTRACT:
A laser includes a narrow bandwidth AR coating for defining a frequency range for laser emission within the laser cavity. Advantageously, the narrow-band AR coating has a very low loss, which can be particularly useful if the gain medium has low gain. The narrow-band AR coating can be used to narrow the laser emission from a broadband gain medium (e.g. Cr:LiSAF), or to select from among discrete transition lines (e.g. Nd:YAG) without the use of cumbersome tuning elements. An etalon may be utilized to further narrow the fundamental wavelength, and the etalon may be substantially uncoated. For a solid state gain medium, the AR coating may be formed on one of the optical faces. A nonlinear element may be included for frequency-conversion, and the AR coating constrains the lasing frequency in the presence of this nonlinear loss and assists in maintaining single frequency operation to provide a stable frequency-converted output.
