【摘要】：短蒸氣室自加熱堿金屬激光器的原理是利用未被增益介質(zhì)吸收的抽運(yùn)光加熱堿金屬蒸氣室。基于三能級(jí)速率方程,建立了半導(dǎo)體激光雙端抽運(yùn)堿金屬激光器的理論模型,研究了增益介質(zhì)長(zhǎng)度、蒸氣室溫度和抽運(yùn)源線寬等參數(shù)對(duì)短蒸氣室自加熱堿金屬激光器輸出激光的影響。研究結(jié)果表明,在普通外腔半導(dǎo)體激光器抽運(yùn)下,增益介質(zhì)長(zhǎng)度為2mm時(shí)可以實(shí)現(xiàn)瓦級(jí)激光輸出,選擇較高的抽運(yùn)光功率可提高自加熱堿金屬激光器的輸出功率。該研究結(jié)果將為自加熱堿金屬激光器的實(shí)驗(yàn)提供理論基礎(chǔ),并可進(jìn)一步拓展小功率堿金屬激光器的應(yīng)用領(lǐng)域。
[Abstract]:The principle of short vapor chamber self-heating alkali metal laser is to heat alkali metal vapor chamber by pumping light which is not absorbed by gain medium. Based on the three-level rate equation, a theoretical model of two-end pumped alkali metal laser with semiconductor laser is established, and the gain medium length is studied. The influence of the temperature of vapor chamber and the linewidth of pump source on the output laser of self-heating alkali metal laser in short vapor chamber. The results show that the output of the watt laser can be realized when the gain medium length is 2mm, and the output power of the self-heating alkali metal laser can be improved by selecting a higher pump power. The results will provide a theoretical basis for the experiments of self-heating alkali metal lasers and can further expand the application field of low-power alkali metal lasers.
