A room-temperature narrow linewidth continuous wave (CW) Tm:Lu 2 SiO 5 laser is investigated by using a Volume Bragg grating and a Fabry-Perot etalon. The output wavelength of 2054.24 nm and a linewidth of 0.12 nm were obtained experimentally, and 1.64W of output power was achieved under an absorbed pump power of 9.2W, corresponding to an optical-to-optical conversion efficiency of 17.8% and a slope efficiency of 23.6%. The laser beam quality was optimized and measured to be M 2 ∼ 1.2 in the x-axis direction and 1.3 in the y-axis direction, respectively. [ABSTRACT FROM AUTHOR]
