氮分子激光器是一种重要的近紫外相干光源。它的输出峰值功率高,脉冲持续时间短,而且结构简单,制造容易,因此受到人们的重视。用它泵浦有机染料激光器,可以获得从近红外到近紫外的连续可调激光输出,是激光喇曼光谱仪的一种理想光源。此外,氮激光器在激光分离同位素、超高速摄影、污染检测以及医疗卫生、农业育种等方面也得到广泛应用。 目前,关于氮激光器的研究主要是进一步提高其输出功率和输出稳定性,为了便于应 Nitrogen laser is an important near-ultraviolet coherent light source. Its output peak power is high, pulse duration is short, and the structure is simple, easy to manufacture, so people’s attention. Using it to pump organic dye lasers, a continuously tunable laser output from near infrared to near ultraviolet can be obtained, making it an ideal light source for laser Raman spectroscopy. In addition, nitrogen lasers are widely used in laser separation isotopes, ultra-high-speed photography, pollution detection and health care, agricultural breeding and so on. At present, the research on the nitrogen laser is mainly to further improve its output power and output stability, in order to facilitate
