Abstract

A wavelength switchable cavity dumped nanosecond (ns) Ho:YAG laser is demonstrated. A rubidium titanyl phosphate (RTP) electro-optic cell is combined with a thin film polarizer (TFP) for cavity dumping operating at 10 kHz repetition rate. By finely rotating the TFP, the intracavity loss for different wavelength peak around 2.1 μm is accurately controlled, and the laser can be selectively operated at 2090.31 nm and 2122.41 nm, respectively. The output characteristics are almost similar for both of the two wavelengths. The pulse width is kept at approximately 4.5 ns. When the incident pump power is 21.8 W, the maximum average output power of 7.3 W is achieved, corresponding to a maximum pulse energy of 0.73 mJ.

波长在2090nm和2122nm之间切换的电光腔倾倒Ho:YAG激光器

介绍了一种波长可切换腔倾倒纳秒（ns） Ho:YAG激光器。将磷酸钛铷（RTP）电光电池与薄膜偏振器（TFP）相结合，用于以10 kHz重复频率工作的腔倾倒。通过对TFP的精细旋转，可以精确控制2.1 μm左右不同波长峰的腔内损耗，实现激光器在2090.31 nm和2122.41 nm的选择性工作。这两个波长的输出特性几乎是相似的。脉冲宽度保持在大约4.5 ns。当入射泵浦功率为21.8 W时，最大平均输出功率为7.3 W，对应的最大脉冲能量为0.73 mJ。

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
