Abstract:

The early years of laser research were characterized by a search for new active media and new transitions. Although progress is continuing in these areas, much of the emphasis has shifted to the advancement of pumping technology. To a considerable extent this shift in emphasis reflects a maturing process taking place in the laser field in response to a fuller understanding of real and potential laser applications. This paper discusses the manner in which pumping technology has evolved and expanded in moving toward higher laser performance and the realization of a broader range of applications. Foremost among these developments are chemical and gas-dynamic excitation in gases, sensitization and spectral matching in optically pumped solids, face-pumped disc technology, and high-pressure discharge excitation. Also described is the manner in which these and other techniques have emerged to advance the state of the art in peak power, average power, efficiency, or other performance parameters. No attempt is made to include intermediate pumping methods involving laser pumped lasers or nonlinear optics.
