摘要: We demonstrated a continuous-wave (CW) self-Raman laser with high conversion efficiency by using Nd:KGW as the Raman crystal based on the Raman shift of 89 cm(-1). The maximum Raman output power was as high as 0.42 W under the pump power of 2.5 W. The diode-to-Stokes optical conversion efficiency was found to be 16.8% which is outstanding among Nd-doped CW self-Raman lasers. Besides, three resonators have been investigated to generate CW self-Raman lasers with different Raman shift of the Nd: KGW crystal at 1077.9 nm (89 cm(-1)), 1162.9 nm (768 cm(-1)), 1181.2 nm (901 cm(-1)), and 1193.7 nm (89cm(-1) + 901cm(-1)). These Raman lasers pave the way to generate more-closely spaced set of CW emission in the green-yellow-orange region.
