摘要: 本文報(bào)道了光柵調(diào)諧的多個(gè)大氣壓CO2激光器的連續(xù)調(diào)諧和頻率牽引的實(shí)驗(yàn)研究。在腔內(nèi)采用了鍺棱鏡擴(kuò)束望遠(yuǎn)鏡或球面反射鏡擴(kuò)束望遠(yuǎn)鏡后,提高了色散腔的頻率選擇性,增大了光柵的受光照射面積,從而實(shí)現(xiàn)了基本無(wú)牽引效應(yīng)的連續(xù)調(diào)諧,并有效地保護(hù)了光柵。

Abstract: Experimental studies on the continuous tuning and frequency pulling in a grating tuning multiatmosphere CO2 laser is reported. Agermanium prism beam expanding telescope or a spherical mirror beam expanding telescope is used in the cavity to improving the frequency selectivity of the dispersion cavity and enlarge the beam exposed area of the grating. In this way, we achieve at continuous tuning with nearly no pulling effect in the continuous tuning and the grating is also effectively protected. -
