摘要：
A laser diode （LD） pumping high-stability 1047 nm TEM00 mode Nd: YLiF4 （Nd: YLF） continuous wave （CW） laser is reported in this letter. The laser output power of 5. 83 W with optical to optical efficiency of 27 % and slope efficiency of 30 % has been achieved. The instability of output power is 0. 36% and spike caused by relaxation oscillation has not been observed in the laser beam. The transverse cross section of laser beam is an ellipse, the diameters of laser beam at output mirror in both directions are 0. 97 mm and 1. 07 mm, respectively. The divergent angles are 0. 936 mrad and 0. 774 mrad, and the values of M2 are 1. 37 and 1. 24, respectively. The polarization degree of laser beam is better than 237: 1.
