Description
In many Raman applications there is a need to detect gases in the low ppb range. The desired sensitivity can be achieved by using a high power laser source in the range of tens of watts. A system combining a build-up cavity to enhance the power and an external cavity laser diode setup to narrow the bandwidth can give the needed power to the Raman spectroscopy system.
