CO2 Laser

open access: yesCO2 Laser
application/pdf In 1961 Polanyi suggested the possibility of using rotating-vibration trasition for laser action of CO2 molecule. Generation in a number of CO2 lines of two rotating-vibration band of the CO2 molecule in the 10μ region was discovered in 1964. This paper reported the review of the investigation and the applications on CO2 laser.
