摘要	In order to realize high-power quasi-continuous wave sodium beacon laser with high-efficiency sum frequency, 1064 nm ring-cavity laser of high-power narrow-linewidth microsecond pulse which restrains relaxation oscillation was studied. A thermally near unstable cavity was adoped to optimize curvature of three-scope ring endoscope, inserting an etalon in cavity to narrow laser linewidth. Using a 1064 nm thin-film polaroid as output mirror of ring cavity and a half wave plate, a continuous adjustable output coupling ratio was realized. Under the condition of 808 nm semiconductor laser with pumping power of 175 W, 1 064 nm laser output with output power of 42 W, beam quality factor M2=1.26, linewidth of 0.2 GHz was acquired. Its repetition frequency is 800 Hz and pulse width is 100 s. The relaxation oscillation of laser pulse was effectively suppressed by inserting 1 064 nm frequency-doubling crystal KTiOPO4 in cavity and using second harmonic effect to rapid weaken high-strength spike pulse sequence.The whole system is pretty simple, which provides the practical and effective technical method for obtaining 1064 nm laser of quasi-continuous wave without relaxation oscillation. 2016, Science Press.
