Abstract:
Laser action in GaAs using a Nd glass laser as a two photon pump was investigated. External mirrors were employed to form the optical cavity. Laser action in GaAs was observed in the following experiments Firstly, the authors observed a narrowing of the emission spectrum. Secondly, the authors examined the output power dependence upon the input power, and measured the threshold power. The main advantage of this method of optical excitation is the possibility of obtaining an inverse population throughout a large semiconductor volume. The advantage of using an external mirror resonator is that it may be possible to Q-switch the GaAs laser and to use the adjustable cavity for various other purposes.
