金属锶蒸气是一种具有多重谱线的激光工作物质，在氦、氖等缓冲气体环境下通过高电压、大电流、高重复率脉冲放电激励，可以实现多重激光振荡．其中最典型的是一价锶离子波长 ４３０．５ ｎｍ／４１６．２ ｎｍ的等离子体复合类型紫色激光和一价锶离子波长 １．０３ μｍ／１．
Metal strontium vapor is a kind of laser working substance with multiple spectral lines. It can achieve multiple laser oscillation by high voltage, high current, high repetition rate pulse discharge excitation in the buffer gas environment of helium, neon and so on. One of the most typical is a monovalent strontium ion with a wavelength of 430.5 nm / 416.2 nm and a violet laser of a complex type and a monovalent strontium ion with a wavelength of 1.03 μm / 1.
