Title: Narrow-band laser with etalon based output coupler
Inventor: ERSHOV ALEXANDER I
IPC: H01S3/225
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To generate a light by a laser at a wavelength providing more high reflectivity by adjusting an etalon based on coupler so as to selectively reflect light at a maximum or minimum spectrum generated by a grating. SOLUTION: An etalon-based output coupler 44 includes two plates having two parallel planes separated by a distance d, and this space is filled with nitrogen. The total reflectivity of the etalon is determined by the interference of optical waves reflected from both parallel surface as a function of the wavelength. If one of reflection peaks conforms a max. of grating, it is reflected so that about 15% of the light at a maximum of grating returns to the laser, but beams greater or smaller by about 1 pm than the max. of grating are not reflected. The laser is capable of generating light at of a wavelength of higher reflectivity through a higher reflectivity than that of a etalon output coupler at one wavelength and with reduced reflectivity at other wavelength.
