Intra-cavity singly resonant optical parametric oscillator based on magnesium-doped periodically poled lithium niobate
摘要
Abstract
To obtain stable laser outputs,bigger turning ranges and higher transfer efficiencies by a simple and compact resonance cavity,a V-type Optical Parametric Oscillator (OPO) pumped by a 1064 nm Nd:YVO4 laser is designed,and broadband wavelength-tunable,continuous-wave (CW)mid-infrared laser sources are obtained.The Nd:YVO4 laser crystal is pumped by a 808 nm semiconductor laser to generate a 1 064 nm laser as the fundamental frequency light,and the V-type cavity is used to control laser spots and to change the grating period and temperature of the PPMgLN to obtain the 2 249 to 3 706 nm tunable idler output.With an 808-nm pump power of 10.5 W and a polarized period of 29.98 μm,a maximum idler output power up to 650 mW at 3 466 nm is achieved under the PPMgLN to be set at 411 K,which shows a better monochromaticity and is corresponding to a center wavelength of 3 466 nm and line width of 2.6 nm.Moreover,when 808 nm pump power is 7.5 W,the maximum optical-to-optical conversion efficiency can be up to 7.73％ and the corresponding output power is 580 mW.关键词
