Review of Diode-Pumped Alkali Vapor Lasers

Host: Bryan Boggs

Since its first demonstration about 10 years ago, the diode-pumped alkali vapor laser (DPAL) has occupied a unique, sometimes controversial position within the laser field.  Originally conceived as large aperture, CW brightness converter for materials processing and directed energy applications these systems have also been pursued as potential short wavelength sources and have stimulated renewed interest in relevant gas phase atomic physics and solid state materials technology.  In this talk I will present the DPAL concept, summarize some early experiments including our own, and consider the challenges to high average power realization.
