Abstract

In this paper we discuss the potential advantages of the alexandrite laser as a light source for long range DOAS monitoring of air quality. The tunable alexandrite output can be frequency converted to provide essentially continuous coverage of the near UV spectrum. The wide tuning range and spectrally narrow output achieved by injection seeding are nearly ideal for several DOAS applications.
