  • Author: Jürgen Niederhofer
Nitrogen lasers have been used for more than 15 years and will no doubt continue to be important in many scientific and industrial applications. However, many applications are moving away from gas lasers to solid-state systems, which offer compactness, improved lifetime, lower cost of ownership, Gaussian beam properties, high repetition rates and increased pulse-to-pulse stability. These characteristics are allowing pulsed diode-pumped solid-state (DPSS) ultraviolet lasers, in particular, to be used for some existing applications, and the technology will likely drive new applications in analytical chemistry, genomics, drug development and forensics. Matrix-assisted laser desorption/ionization (Maldi) mass spectrometry and laser microdissection already are benefiting from this technology.
