Quasi Monolithic Single Frequency Titanium-Doped Sapphire Ring Laser

9360877 Pierce Cygnus Laser提出用一种紧凑的、基于掺钛蓝宝石（Ti:S）的全固态激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源。最近，连续波频率加倍的二极管泵浦Nd:YAG激光器的效率和输出功率的显著提高，使该系统在短期内可行，具有吸引人的整体壁塞效率。我们的准单片单频Ti:S激光器的尺寸与稳定的单模二极管激光器系统大致相同，但它具有固有的频率稳定性，大大降低了系统的复杂性，提高了主动稳定系统的可靠性。它将成为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. ***
