| 摘 要： | 针对组合式片状放大器(MSA)只能进行被动热恢复的现状,研究了放大器中各关键单元器件的热恢复时序.结果表明,抽运结束后,钕玻璃和隔板玻璃之间的热传递存在交互变化的特点,在隔板玻璃升温之前采用主动冷却可消除钕玻璃主要热源.提出了采用延时全腔水冷的设计,从而在不影响放大器效率的基础上实现了主动热恢复,并就典型放大器给出了延时参数.

| Abstract: | Theory simulation and experiment was carried out for thermal recovery of the multi-segment amplifiers (MSA). New design of time delayed water cooling was developed isolate the heat transferred from flashlamp to Nd glass which contributes more than half of the unwanted heat of Nd glass. The delayed time of 4 × 2 × 3 amplifiers is about 10 minites. |
