摘要 | A high-power unstable resonator semiconductor laser (14) emits optical output of greater than 50 mW in a wavelength range of 700-1100 nm. A grating (116,136) may be positioned external to URSL (14) to control the spectral bandwidth and wavelength output of the waveguide pumping beam (74). Alternatively, URSL (14) may be fabricated with a distributed feedback (DFB) grating or a distributed Bragg reflector (DBR). Infrared waveguide pumping beam (74) generated by such a high-power unstable resonator semiconductor laser (14) is coupled into a nonlinear waveguide (28) and converted to visible or near ultraviolet output (100) through the process of second-harmonic generation. |
其他摘要 | 高功率不稳定的谐振器半导体激光器(14)在700-1100nm的波长范围内发射大于50mW的光输出。光栅(116,136)可以位于URSL(14)的外部,以控制波导泵浦光束(74)的光谱带宽和波长输出。或者,URSL(14)可以用分布式反馈(DFB)光栅或分布式布拉格反射器(DBR)制造。由这种高功率不稳定谐振器半导体激光器(14)产生的红外波导泵浦光束(74)耦合到非线性波导(28)中,并通过二次谐波产生过程转换成可见或近紫外输出(100)。 |
