  High-Accuracy Laser Wavelength Meter
 

The 671 Series laser wavelength meter is the best way to measure the absolute wavelength of CW lasers that operate from the visible to the mid-IR. This system provides real-time laser wavelength information with an accuracy as high as ± 0.0001 nm. Continuous calibration with a built-in wavelength standard ensures the reliable accuracy that is needed to generate the most meaningful experimental results.

FM Spectroscopy With Tunable Diode Lasers
 
By Newport

Frequency-modulation spectroscopy (FMS) offers high sensitivities and a simple setup, especially with tunable diode lasers. Tunable diode lasers provide a tunable output that can be modulated and are used in the rapidly growing field of TDLAS (tunable diode laser absorption spectroscopy). This application note explains the essential elements of the physics of FMS and the basic physics of FM “saturation” spectroscopy.
