    • Thermo-optic tuning apparatuses and techniques that may be used in external cavity lasers are provided. A wavelength selection device may be placed in the external cavity and may include a thermally responsive substrate and tunable optical elements extending therefrom. Heating and heat monitoring actuators may be formed in the substrate itself, with the tunable optical elements being mechanically positioned in the recesses of the substrate for thermo-optic tuning. In some examples, a separate optical path length adjustment element is also placed in the thermally responsive substrate, or elsewhere, for separate frequency tuning. This adjustment element may be part of a control that is detangled from the normal servo controls used in laser tuning.
    • 提供了可用于外腔激光器的热光调谐装置和技术。 波长选择装置可以放置在外部空腔中,并且可以包括热响应基板和从其延伸的可调光学元件。 加热和热监测致动器可以形成在基板本身中,其中可调光学元件机械地定位在基板的凹部中用于热光学调谐。 在一些示例中,单独的光程长度调节元件也放置在热响应衬底或其他地方,用于单独的频率调谐。 该调整元件可以是与激光调谐中使用的普通伺服控制器相关的控制的一部分。
