Abstract
A laser system comprises a pump diode, fiber, relay optics, and a microchip laser crystal. The pump diode produces light at a first wavelength. The fiber receives the light from the pump diode and produces a round, homogeneous light spot at an output of the fiber. The relay optics receives the light from the fiber. The microchip laser crystal receives the light from the relay optics and produces a linearly polarized single frequency output at a second wavelength. The microchip laser crystal includes a first layer and a second layer. The first layer absorbs the light at the first wavelength and emits light at the second wavelength. The second layer receives the light at the second wavelength and either provides a polarization dependent loss at the second wavelength or maintains a polarization of the light at the second wavelength.
