Abstract
A COgas laser device according to the present invention amplifies COlaser light that oscillates repeatedly in short pulses having a pulse width of 100 ns or less, and cools a CO2 laser gas which is excited by continuous discharge by circulating the CO2 laser gas by means of forced convection. Therein, an angle θ defined by the optical axis of the amplified COlaser beam and the flow direction of the COlaser gas caused by the forced convection is determined by both a discharge cross sectional area and a discharge length of a volume in which the COlaser gas is excited by discharge, whereby increasing the gain of pulsed laser to achieve pulsed laser light having an extremely high average output power.
