Study the electrical and optical characteristics of diode pumped solid state frequency doubled (DPSSFD) semiconductor laser
Abstract:<br /> The electrical and optical characteristics of diode pumped solid state frequency doubled (DPSSFD) semiconductor laser had been studied. Five different techniques had been used to calculate the laser threshold are (L-I, V-I, dV/dI vs I, IdV/dI vs I, L/(dL/dI) vs I). The calculat...

| description | Abstract:<br /> The electrical and optical characteristics of diode pumped solid state frequency doubled (DPSSFD) semiconductor laser had been studied. Five different techniques had been used to calculate the laser threshold are (L-I, V-I, dV/dI vs I, IdV/dI vs I, L/(dL/dI) vs I). The calculated values of threshold current had been found varying from 96mA to 99mA.While the series resistance of the laser diode was determined above threshold by using three methods (V-I, dV/dI vs I, IdV/dI vs I) and the value estimated between (6.3 ~ 6.6). The quantum differential efficiency D had been found to be high and equal to 0.66W/A. Maximum optical power emitted from DPSSFD laser is 14mW.The electrical ideality factor and optical ideality factor should be nearly equal and they are about unity. |
