Bandwidth and tuning range of an ArF laser measured by 1 + 1 resonantly enhanced multiphoton ionization of NO

Abstract
The tuning range and bandwidth of an ArF laser were measured using 1 + 1 resonantly enhanced multiphoton ionization of NO. Operated as an injection-seeded oscillator/amplifier combination, the tuning range was 51,560–51,810 cm−1; operated with single pass amplification of the oscillator, the tuning range was 51,560–51,765 cm−1. In both cases, the laser bandwidth, determined from the linewidth, was 0.21 ± 0.06 cm−1. Rotational lines in the β(7,0), γ(3,0), and (0,1) bands were observed including several previously unreported lines.
