Abstract
The major experimental obstacles encountered in performing diode laser FM Spectroscopy (FMS) are: (1) optical fringes from transmissive optics; (2) lack of optical power; (3) feedback-induced noise and excess laser noise; (4) thermal drift of signal and background; (5) laser RAM. Effective methods of dealing with all these problems must be devised to achieve quantum limited detection sensitivity.
