全固态被动调Q皮秒激光技术研究进展

全固态被动调Q激光技术在产生皮秒脉冲方面有较快发展。与锁模激光器相比,被动调Q皮秒激光器成本低、结构简单、易于校准光路,避免了锁模激光器结构复杂、机械敏感度高、光路校准困难等缺点,并且同样能够输出单脉冲能量可观、重频合适的皮秒量级短脉冲,因此拥有较高的实用价值。本文讨论了全固态被动调Q皮秒激光技术领域的两种典型技术路线以及对调Q皮秒脉冲输出的后续处理技术,包括非线性技术和激光放大技术等,并介绍了国内外相关研究团队在该领域所做的工作及其突破性进展。

Science Letters:Controllable high repetition rate gain-switchedNd:YVO_4 microchip laser

We demonstrated a monolithic, compact, diode-pumped gain-switched Nd:YVO4 laser at 1.064 μm wavelength with controllable repetition rate of 1 Hz to 25 kHz. Stable gain-switched pulse train with maximum repetition rate of 25 kHz and pulse width of 16 ns was obtained.
