我们报告了在二阶准相位匹配LiNbO(3) 通道波导中通过直接二极管激光倍频产生高效（22%/W）蓝光。我们解决了直接二极管激光器倍频的几个关键问题，包括输入耦合、相位匹配带宽，特别是高功率二极管激光器的光谱模式结构对频率转换效率的影响。
We report efficient (22%/W) blue-light generation by direct diode-laser frequency doubling in second-order quasi-phase-matched LiNbO(3) channel waveguides. We address several critical issues of direct diode-laser doubling, which include input coupling, phase-matching bandwidth, and, in particular, the effect of the spectral mode structure of a high-power diode laser on the frequency-conversion efficiency.
