Spectroscopic laser diodes are key components in analyzers based on tunable diode laser absorption spectroscopy (TDLAS). VCSELs, DFB lasers, quantum cascade lasers (QCLs), and lead salt (PbSe) lasers are all available for delivery.
Single-mode VCSEL at 760 and 948 nm
Single-mode DFB laser diodes from the Heinrich Hertz Institute for Communication.
The laser wavelength is stabilized by a volume bragg grating (VBG) to +/- 0.2 nm to render it virtually temperature independent.
