Abstract

A transverse-pumped sodium vapor active element has been developed. A possibility of lasing at resonant transitions upon active medium excitation using nanosecond pulses of various energies and spectral conditions has been experimentally investigated. The medium was pumped using a dye laser and a CuBr laser. Radiation was detected on sodium D lines when pumping with CuBr laser yellow emission line.
