METHOD FOR STABILIZING THE WAVELENGTH OF A LASER AND ARRANGEMENT FOR IMPLEMENTING SAID METHOD

摘要

The invention relates to a method and an arrangement which make it possible to measure a ratio (p2/P3) dependent on the overall optical power (P0) of the laser (1) between a power (p2) from a fraction (P2) of the overall power (P0) filtered by a filter, (2) said overall power (p2) substantially containing only the wavelength ( lambda ) to be stabilized, and a second fraction (P3). The value thus obtained is then compared with a desired value (S0). The temperature (T) of the laser (1) is regulated according to the desired value (S0) if the resulting value does not correspond with the desired value (S0).
