| Abstract: | Conclusion We have demonstrated the modulation of laser around threshold for the observation of relaxation oscillations in a semiconductor
diode laser. The oscillations frequency for the diode laser D1 was 1.5 kHz whereas the oscillations frequency corresponding to the laser from laser pointer D2 was 227 kHz. We have also observed the variation in damping time and relaxation frequency of both the lasers as a function
ofx. In fact a classroom exercise can be taken up easily to do the parametric characterisation. |
