摘要
根据ＣＯ＿２分子振—转光谱在红外有丰富谱线的特点，设计了输出强线为３Ｗ，弱线为２００ｍＷ的可调谐激光器，并经实验证明了设计的正确性。
In this paper the authors have designed a laser which has 3W strong.output beam，2000mW weak beam and can be regulated The design based on the character that the vi- bration-tuming spectrum of the carbon dioxide molecula includes more rich spectrum -lined in ultrated band The rightness of the design has been proved by experiments
