摘要

本文介绍了一种利用体全息光栅实现波长稳定的高功率二极管激光模块。高功率二极管激光器模块通常具有相对较宽的光谱宽度,约为3至6nm。此外,中心波长会随着温度和驱动电流的变化而发生位移,这对吸收带宽较小的泵浦应用有阻碍作用。高功率二极管激光器模块的波长稳定是提高窄吸收带宽固体激光器抽运效率的重要手段。

Wavelength stabilized high-power diode lasers and modules
This presentation covers high-power diode laser modules with enhanced spectral brightness by means of volume holographic gratings for wavelength stabilization. High-power diode laser modules typically have a relatively broad spectral width of about 3 to 6nm. In addition the center wavelength shifts by changing the temperature and the driving current, which is obstructive for pumping applications with small absorption bandwidths. Wavelength stabilization of high-power diode laser modules is an important means for more efficient pumping of solid-state lasers with a narrow absorption bandwidth.
