Single-mode frequency tuning of a high-pressure photopreionized CO2-laser

Single-mode frequency tuning of a pulsed high-pressure photopreionized CO2-laser with laser linewidth less than about 0.001/cm and peak power up to 100,000 W is reported. Two regimes of synchronous frequency scanning of the resonator mode by a piezoceramic transducer and mode-selecting etalon by cor...

Description
Summary:Single-mode frequency tuning of a pulsed high-pressure photopreionized CO2-laser with laser linewidth less than about 0.001/cm and peak power up to 100,000 W is reported. Two regimes of synchronous frequency scanning of the resonator mode by a piezoceramic transducer and mode-selecting etalon by corresponding angle tilting are carried out in the spectral interval covering the free spectral range of the used etalons. Contours of isolated lines and high-resolution absorption spectra of ethylene are presented.
