Abstract

We have developed injection-seeded terahertz-wave parametric generator pumped by a amplified microchip Nd:YAG laser. This generated high-peak-power, narrow-linewidth and tunable terahertz-wave with injection seeding by an amplified external cavity diode laser. We observed tunable terahertz-wave, peak power of more than 120 W and linewidth of less than 10 GHz by calibrated pyroelectric detector.

微芯片Nd:YAG激光器泵浦的高峰值功率窄线宽太赫兹波产生
研制了用微芯片Nd:YAG激光器泵浦的注入种子太赫兹波参量发生器。通过放大的外腔二极管激光器注入播种,产生了峰值功率高、线宽窄、可调谐的太赫兹波。通过标定的热释电探测器观测到可调谐太赫兹波,峰值功率大于120w,线宽小于10ghz。
