D62-075 Effective December 31, 2011, LASER COMPONENTS will discontinue production of cryogenically cooled diode lasers in the middle IR range. For our long-time customers in academic circles we will extend this offer to place one last order until March 31, 2012. The first PbSe lasers were produced in the late ‘60s; they reached their technological heyday in the ‘80s and early ‘90s. Both the scientific fundament and the device concept for high-resolution gas measurement technology via tunable diode laser spectroscopy (TDLS) originated here. We have accompanied lead salt laser technology almost 20 years and made important contributions: increased reliability, demonstration of pulsed operation at room temperature, and the construction of DFB lasers based on lead salt technology. The necessity of cryogenic cooling in single-mode operation has always hindered wide industrial use. Consequently, TDLS did not achieve its commercial breakthrough until used in the NIR range. A list of IR lasers available in stock can be found on our web site. Use the web code to access the list.
