Abstract
A low-noise micro-chip laser includes a diode pump, a gain medium, a nonlinear crystal, and a birefringent material. The gain medium can receive the energy from the diode pump and generate a laser beam at a fundamental wavelength. The nonlinear crystal can generate a frequency-doubled laser beam in response to the laser beam at the fundamental wavelength. To reduce noise in the frequency-doubled laser beam, the birefringent material and the nonlinear crystal in combination are designed to function as a quarter wave plate at the fundamental wavelength.
