Temperature-tunable, single frequency microcavity lasers fabricated from flux-grown YCeAG:Nd

Abstract
Data are presented on a single‐frequency, diode‐pumped, microcavity YCeAG:Nd laser. The maximum output power was 45 mW in continuous operation, limited by the available pump power of 250 mW. The output was single‐frequency, TEM00 at all powers. The lasing frequency was continuously temperature‐tunable over a range greater than 180 GHz, with a stability of better than 10 MHz.
