Transversely excited N2O sequence band laser

Abstract

Sequence band operation of a transversely excited nitrous oxide laser is reported for the first time. The sequence laser could be tuned to each V-R line from R(25) to R(14) and from P(14) to P(26) in the 10.7-μm band. Output energies were 10 μJ–1 mJ. Improved stability of the discharge at high specific energy loading and use of an intracavity hot cell made sequence band oscillation possible.
