Gain medium matching for mid- and far-infrared dual-band laser
摘要
Abstract
The DF and CO2 laser mediums matching for a mid- and far-infrared dual-band laser was studied. Theoretical a-nalysis of the gain distribution of the two mediums shows that, compared with the CO2 laser medium, the peak gain position of DF laser medium is more ahead, and the gain zone length is much shorter. Then a dual-band laser was designed and manufactured, with the position of the CO2 injection orifices adjustable, and the match between the peak gain positions of DF and CO2 laser medi-ums can be achieved by the position difference of the D2 and CO2 injection orifices. The experiment shows that the design is effective, and the optimum position of the common optical axis of this dual-band laser is 3 mm downstream of D2 orifices and 33 mm downstream of CO2 orifices, where the output powers of both bands are close to their maxima.关键词
