We report on an efficient continuous-wave Cr(3+):LiSrAlF(6) ring laser pumped by the near-diffraction-limited output of an injection-locked 665-nm broad-area diode laser. With an absorbed pump power of 120 mW the ring laser generates 22 mW of single-mode 855-nm radiation with a spectral linewidth of less than 10 MHz. Unidirectional operation and longitudinal-mode control of this ring laser is achieved by injection of 855-nm diode-laser radiation into the ring cavity. Optical feedback of ring-laser radiation into the diode laser narrows the diode laser's linewidth and locks its frequency to a resonance of the ring resonator.
我们报道了一种由注入锁定的665纳米宽面二极管激光器的近衍射极限输出泵浦的高效连续波Cr(3+):LiSrAlF(6)环形激光器。在吸收泵浦功率为120毫瓦的情况下，该环形激光器产生22毫瓦的单模855纳米辐射，光谱线宽小于10兆赫兹。通过将855纳米二极管激光辐射注入环形腔，实现了该环形激光器的单向运行和纵向模式控制。环形激光器的辐射光反馈到二极管激光器中，可使二极管激光器的线宽变窄，并将其频率锁定到环形谐振器的一个谐振频率上。
