Abstract

Single-frequency output power of 35 mW has been observed in 3.0% doped Nd:YVO₄ pumped with a 200-mW laser diode. The single-frequency operation is due to the spatial overlap of longitudinal modes at the surface of a mirror in the laser cavity where the material is pumped. The strong absorption coefficient at 808.7 nm and narrow bandwidth of the Nd:YVO₄ only allow a single laser mode to operate. The effect is modeled theoretically and compared with the experiment
