Abstract
Spectroscopic properties and self-frequency-doubling laser performance are presented for (Yb:YCOB) crystals oriented for type I second-harmonic generation in the plane. In a plane-concave cavity 10 cm long, up to 330 mW of green light (544.5 nm) is obtained for 14.7 W of laser diode incident pump power. Broad emission bands and weak anisotropy in the 1060–1100 nm range between the two eigenstates of polarization may explain the instability of the self-frequency-doubled output power.
