Laser carbon monoxide:

Laser carbon monoxide, CO-laser, a gas laser, with pulsed radiation in the active medium of which is for receiving coherent electromagnetic waves of the infrared range is used carbon monoxide (CO).

The principle of operation of a CO laser based on the vibrational-rotational laser transitions. In these lasers use transitions between two vibrational levels of the molecule.

Laser monoxide carbon emits electromagnetic waves in the infrared range with a wavelength of from 2.5 to 4.29 microns and from 4.8 to 8.3 microns.

CO-laser is one of the most powerful lasers, operating in pulsed mode. Its efficiency reaches 60 % and output power exceeding 100 kW.

In order to achieve such high efficiency WITHlaser, it is necessary to cool to low temperatures – up to 77-100 K (to -196,15 – -173,15 OS). At room temperature its efficiency is about 20-30 %. Therefore, the device CO-laser system provides cooling. As the pumping source is used , electric discharge or chemical reaction.

Laser carbon monoxide is used for material processing (laser engraving, laser welding , etc.), photoacoustic spectroscopy.
