Quasi Monolithic Single Frequency Titanium-Doped Sapphire Ring Laser

9360877皮尔斯天鹅座激光计划用一种基于钛掺杂蓝宝石(钛：S)的紧凑型全固态激光光源取代半导体激光器作为高分辨率激光光谱和高精度原子钟的光源。最近，二极管泵浦的连续波倍频激光器的效率和输出功率有了惊人的提高，这使得该系统在短期内是可行的，具有诱人的整体壁塞效率。我们的准单片单频钛S激光器与稳频单模半导体激光器系统的尺寸大致相同，但它具有固有的频率稳定性，大大降低了有源稳频系统的复杂性，提高了系统的可靠性。它将是下一代原子钟和其他频率标准的理想来源。***

9360877 Pierce Cygnus Laser proposes to replace the semiconductor laser as a source for high resolution laser spectroscopy and high precision atomic clocks with a compact, all solid state laser source based upon titanium-doped sapphire (Ti:S). Recent spectacular improvements in the efficiency and output power of a continuous-wave frequency doubled diode pumped Nd:YAG laser has made this system feasible in the near term, with attractive overall wall plug efficiency. Our quasi monolithic single frequency Ti:S laser is approximately the same size as a stabilized single mode diode laser system, but it is intrinsically frequency stable, dramatically reducing the complexity and increasing the reliability of the active stabilization system. It will be an ideal source for the next generation of atomic clocks and other frequency standards. ***
