讨论了用于二极管泵浦固体激光器的片上光栅稳定半导体激光器的发展。在808nm、976nm和1532nm波长处，二极管激光器通过内部光栅稳定，中心波长公差为±1nm， FWHM < 1-2nm，温度调谐系数< 0.09 nm/°C。我们还报告了传导冷却棒、堆和光纤耦合模块的连续和QCW操作。仿真结果表明，片上稳定泵源的性能优于标准泵浦方案。在激光性能的比较显示了典型的DPSS配置。
The development of on-chip grating stabilized semiconductor lasers for diode pumped solid state lasers is discussed. The diode lasers, specifically at wavelengths of 808nm, 976nm, and 1532nm are stabilized via internal gratings to yield a typical center wavelength tolerance of ± 1nm, FWHM of < 1-2nm, and a temperature tuning coefficient of < 0.09 nm/°C. We also report on the CW and QCW operation of conduction cooled bars, stacks, and fiber coupled modules. Simulations show that on-chip stabilized pump sources yield performance improvements over standard pumping schemes. A comparison in laser performance is shown for typical DPSS configuration.
