描述了由光纤放大二极管激光器泵浦的单谐振连续波光学参量振荡器（cw-OPO）。泵浦源的调谐允许 OPO 输出在 29 ms 内连续调谐到 110 GHz 以上，无需跳模。还获得了在 3.4 微米区域内超过 20 纳米的不连续泵浦调谐。通过测量甲烷吸收光谱证明了快速、连续的惰轮调谐。我们相信这是由光纤放大二极管激光器泵浦的单谐振 OPO 的第一个示例，并且无跳模调谐范围是 CW-OPO 报道的最高值。
A singly-resonant continuous-wave optical parametric oscillator (cw-OPO) pumped by a fiber-amplified diode laser is described. Tuning of the pump source allowed the OPO output to be tuned continuously, without mode-hops, over 110 GHz in 29 ms. Discontinuous pump tuning over 20 nm in the region of 3.4 microm was also obtained. The rapid and continuous idler tuning was demonstrated by the measurement of a methane absorption spectrum. We believe this to be the first example of a singly-resonant OPO pumped by a fiber-amplified diode laser and the mode-hop free tuning range to be the highest reported for a cw-OPO.
