Abstract
When a potassium vapor cell surrounded by a stable cavity is pumped with a pulsed dye laser near the 42P resonances, Stokes and anti-Stokes lasing due to Stimulated Electronic Raman Scattering (SERS) is generated. When the pump is tuned about halfway between the fine structure levels of the 42P state, an effcient hyper-Raman process dominates, resulting in tunable laser radiation near 769 nm with a slope effciency of about 10.4%. Up to 12 mW of red light is produced at a pump input of 232 mW. The threshold for the hyper-Raman process is about 60 mW. This type of laser may be useful for beam propagation experiments where a tuneable probe beam spectrally close to the main beam is desired.
