A lead bromide laser operating at 722.9 and 406.2 nm

摘要

A self-heated laser, operating on the atomic lead transitions at 722.9 and 406.2 nm is reported. The free lead atoms were produced by electric-discharge dissociation of lead bromide which was generated in situ by flowing a Ne-HBr gas mixture over molten Pb in the laser tube. The experimental technique may be applied readily to a number of metal-vapor lasers. Also reported is stable high-PRF operation on the 406.2 nm transition of lead.
