【Abstract】 A 3W diode end-pumped Nd: LMA laser operating at 1054urn is reported in this paper. The pump source is a 3W laser diode array (SDL-2342--P1). The laser medium was a 9mm long, 5mm diameter plane-Brewster rod of 10% doping level of Nd ions. The plane surface was coated to give high reflectivty at the lasing wavelength of 1054urn, and high transmission at the pump wavelength of 798urn. Transmission of output coupler and cavity length are 10% and 0. 95m, respectively. A 39cm ROC turning mirror was designed to compensate the astigmatism caused by the Brewster angle of the laser fod. The compensation angle of ROC mirror is 6. 5". The output power of 230 mW with slope efficiency of 38% and total optical efficiency of 9. 5% at 1054urn are obtained by three-mirror folded astigmatism compensation cavity.更多还原
