| Pulsed
CO2 and N20 Lasers with High
Output Pulse Energy |

|
The basic physical principles and design concepts
were found by Crystaltechno
for the manufacturing of high power
pulsed CO2 and N2O lasers.
The basis of the design are the new physical
principles of volume self-sustained discharge
initiation in high pressure gases as well as the
results of extensive studies of technical aspects
of construction, operation and manufacturing of
pulsed molecular gas lasers. The design ideas
and experimental models of CO2 and
N2O lasers with wide range of output
characteristics are existed.
The lasers differ from the existing commercial
products on the market by the simplicity and lover
cost in production; some of them have no serial
analogs on the market.

| Features |
- The electrodes with special shape are not
used in the design
- The level of operation voltage of pulsed pumping
generator is
relatively low
- No stringent requirements to the discharge
circuit; inductance exist
- All models are operating in self-sustained
discharge mode
- No electron beams used, even at very high
energies.
