Abstract
A gas laser device. The device includes a laser chamber having at least one active gas and a device for purifying gas. The purified gas is in communication with the free exchange of gas with the chamber. This device may be used with high powered gas lasers.
Claims11
A gas laser device comprising:
- a laser chamber containing at least one active gas;
- and
- gas purification means in communication with free exchange of gas with said as chamber, wherein said gas purification means being in communication with the free exchange of gas is defined as no gas circulation being imposed so that any one of a pump and a compressor is not needed in order for the gas to be brought to said gas purification means, the gas being brought to said gas purification means only by opening valves so that the gas may flow naturally due to any one of gravity and Brownian displacement of particles.
A purification process for a gas laser chamber, said process comprising the steps of:
- putting said laser chamber into communication with free exchange of gas with at least one gas purification means, wherein the free exchange of gas is defined as no gas circulation being imposed so that any one of a pump and a compressor is not needed in order for the gas to be brought to said gas purification means, the gas being brought to said gas purification means only by opening of valves so that the gas may flow naturally due to any one of gravity and Brownian displacement of particles.
