Abstract
A total output power of 25. 5W was achieved after optimizing the transmissivity of the output mirror and the design of the output w indow in the middle infrared and long infrared dual-band( 3 ~ 5 μm 8 ~ 12 μm) laser driving by tw o glow discharge tubes. Pow er in either single band is greater than 10W. The transverse mode of DF and CO2laser beam in the middle and long infrared band is TEM00and TEM20,respectively. An output power of 15. 4W was obtained for TEM00fundamental mode selected w ith a Φ8mm diaphragm. The dual-band laser can w ork as light source for research of dual-band or multi-band infrared detector arrays and the related systems.
