论文摘要
我们开发了一个简单的三个阶段扩增的可调CW二极管激光系统，该系统包括：littrow配置主激光器，用二甲状腺原子蒸气激光锁（DAVLL）稳定频率，一种声学频率变速杆（AOM），一个不可或缺的Slave Laser and tave lasected Slave Laser和Tepaper amplefifififififier（aom）。从奴隶放大频率偏移的光束，并抑制其强度对AOM载体频率的强依赖性，从而充当有效的光学限制器。梁在TA中进一步扩增。系统在780 nm处运行，输出功率高于700 mW，时间平均为0.6 MHz，并且频率漂移低于2 MHz/h。主量为2 GHz的无单跳调谐范围，Davll允许锁定点可调性在400 MHz的范围内。通过应用的AOM模型确定的罚款（具有数十个kHz精度）调谐范围跨越了70 MHz。给出了该系统的详细描述，并测试了其性能。基本组件是在我们的实验室设计和制造的。
We developed a simple three-stage amplifying tunable cw diode laser system that comprises: a Littrow configuration master laser, frequency stabilized with a dichroic atomic vapor laser lock (DAVLL), an acousto-optic frequency shifter (AOM), an injection-locked slave laser and a tapered amplifier (TA). Slave amplifies the frequency-shifted beam and suppresses (within 0.5%) the strong dependence of its intensity on the AOM carrier frequency, thus acting as an efficient optical limiter. The beam is further amplified in TA. System operates at 780 nm, with an output power above 700 mW, a time-averaged linewidth of 0.6 MHz, and a frequency drift below 2 MHz/h. The mode-hop-free tuning range of the master amounts 2 GHz, DAVLL allows a lock point tunability in the range of 400 MHz. The fine (with some tens of kHz precision) tuning range spans 70 MHz, determined by the AOM model applied. A detailed description of the system was given and its performance was tested. The basic components were designed and manufactured in our lab.
