A compact high-power yellow-green continuous wave (CW) laser source based on second-harmonic generation (SHG) in a 5% MgO doped periodically poled congruent lithium niobate (PPLN) waveguide crystal pumped by a quantum-dot fiber Bragg grating (QD-FBG) laser diode is demonstrated. A frequency-doubled power of 90.11 mW at the wavelength of 560.68 nm with a conversion efficiency of 52.4% is reported. To the best of our knowledge, this represents the highest output power and conversion efficiency achieved to date in this spectral region from a diode-pumped PPLN waveguide crystal, which could prove extremely valuable for the deployment of such a source in a wide range of biomedical applications.
展示了一种基于5%氧化镁掺杂的周期极化同成分铌酸锂（PPLN）波导晶体中的二次谐波产生（SHG）的紧凑型高功率黄绿连续波（CW）激光源，该晶体由量子点光纤布拉格光栅（QD-FBG）激光二极管泵浦。报道了在波长560.68 nm处倍频功率为90.11 mW，转换效率为52.4%。据我们所知，这代表了迄今为止从二极管泵浦的PPLN波导晶体在该光谱区域所实现的最高输出功率和转换效率，这对于在广泛的生物医学应用中部署这样的光源可能极具价值。
