High-power, single-frequency diode-pumped Nd:YAG microcavity lasers at 1.3 μm

A single-frequency output power of 210 mW on the 1.3 μm transition was obtained from a monolithic YAG laser doped with 4.2% Nd. Lasers fabricated from high Nd-concentration YAG crystals oscillated simultaneously on the 1.319 and 1.338 μm lines at high pump power, but in a single axial mode at both w...

Description
Summary:A single-frequency output power of 210 mW on the 1.3 μm transition was obtained from a monolithic YAG laser doped with 4.2% Nd. Lasers fabricated from high Nd-concentration YAG crystals oscillated simultaneously on the 1.319 and 1.338 μm lines at high pump power, but in a single axial mode at both wavelengths. The oscillation frequency was continuously temperature-tunable at a rate of 3.6 GHz/ °C over a range of 170 GHz (10 Å). The emission was linearly polarized with an extinction ratio ≳1000:1. In two-wavelength operation, the 1.319 and 1.338 μm transitions were orthogonally polarized.
