EXTERNAL CAVITY WAVELENGTH STABILIZED RAMAN LASERS INSENSITIVE TO TEMPERATURE AND/OR EXTERNAL MECHANICAL STRESSES, AND RAMAN ANALYZER UTILIZING THE SAME

摘要

In one form of the invention, there is provided an external cavity wavelenght stabilized laser system comprising: a platform; a laser mounted to the platform with a laser mount; a diffractor mounted to the platform with a diffractor mount; and a lens mounted to the platform with a lens mount between the laser and the diffractor so as to transmit light therebetween; wherein the wavelenght of the laser is determined by (i) the angle of incidence of the light of the diffractor, and (ii) the diffractor characteristics of the diffractor; and wherein the system components are selected so that (i) a change in the angle of incidence of the light on the difference due to a change in the temperature of the system components substantially offsets (ii) a change in the diffraction characteristics of the diffractor.
