System for rapidly tuning a low pressure pulsed laser |
摘要 |
A rapidly tunable low pressure laser comprised of a one electrode pair low pressure CO2 gas laser gain cell and intra-cavity quarterwave plate and Q-switch. The cell has a fixed laser output coupled at one end of the laser cavity and at the other end of the cavity a wavelength switching device which changes laser lines in less than 1x10-3 mu sec, i.e. changes the wavelengths in less than 1 millisecond within the low pressure laser, to produce at least two quick pulses of different wavelengths at a separation of 1 millisecond. The wavelength switching device is comprised of a fast rotating mirror on the laser optical axis and a fixed grating, or a rotating grating on the optical axis.
