Wavelength stabilization of tunable lasers by current modulation

   
   

Apparatus and method for stabilizing the wavelength of a tunable laser to a target wavelength, by correspondingly adjusting the electrooptical performance of the laser's gain medium, whereby to eliminate the frequency shift due to vibrational factors. The electrooptical performance of the laser's gain medium is adjusted, in the case of an electrically pumped laser, by changing the injection current used to pump the laser; and the electrical performance of the laser's gain medium is adjusted, in the case of an optically pumped laser, by changing the intensity of the pump laser used to energize the laser. The system is implemented with a feedback mechanism.

Instrumento e método para estabilizar o wavelength de um laser ajustável a um wavelength do alvo, correspondingly ajustando o desempenho electrooptical do meio do ganho do laser, por meio de que para eliminar a freqüência desloque devido aos fatores vibrational. O desempenho electrooptical do meio do ganho do laser é ajustado, no exemplo de um laser eletricamente bombeado, mudando a corrente de injeção usada bombear o laser; e o desempenho elétrico do meio do ganho do laser é ajustado, no exemplo de um laser ótica bombeado, mudando a intensidade do laser da bomba usado energizar o laser. O sistema é executado com um mecanismo do gabarito.
