摘要	A diode pumped doubling system employs a pump diode, a crystal and doubler in a laser cavity with the diode and is operated in a pulsed or low duty cycle pumping regimen, while the cavity length is sufficiently short to stabilize the transient responses to pulsed diode operation and produce stable and known or controlled energy output under the non-CW pumping regimen. The construction allows stable output to be maintained with much looser temperature control, and to be achieved during the initial turn-on interval of the laser diode. In a preferred embodiment, the device employs a doubler which is clamped across its non-critical axis, and is operated with a control system which creates isotherms in the active mode volume. The controller operates one or more separate heat sources and/or sinks to preheat the diode source or doubling crystal to maintain an oriented thermal gradient, and the rate or direction at which the isotherm migrates across the mode volume is controlled in accordance with the forthcoming pulse sequence to maintain effectively stable conditions during laser operation. The thermal control system may include sink, heater and control elements for pre-heating the laser diode before actuation, and during quiet intervals.
其他摘要	二极管泵浦倍频系统在二极管的激光腔中采用泵浦二极管，晶体和倍增器，并以脉冲或低占空比泵浦方式工作，而腔长足够短以稳定对脉冲二极管操作的瞬态响应并且在非CW泵送方案下产生稳定且已知或受控的能量输出。该结构允许通过更宽松的温度控制来保持稳定的输出，并且在激光二极管的初始接通间隔期间实现。在一个优选实施例中，该装置采用一个倍增器，该倍增器被夹在其非临界轴上，并且用一个控制系统操作，该控制系统在有效模式体积中产生等温线。控制器操作一个或多个单独的热源和/或吸收器以预热二极管源或加倍晶体以保持定向的热梯度，并且根据即将到来的脉冲控制等温线在模式体积上迁移的速率或方向。在激光器操作期间保持有效稳定条件的顺序。热控制系统可包括用于在致动之前和在安静间隔期间预热激光二极管的接收器，加热器和控制元件。
