Study of the influence of the magnetic field on MQW laser through image processing

This paper represents the ability of Multiple Quantum Well (MQW) Laser for remote sensing by image processing of the laser beam cross sectional using the digital camera and personal computer. The magnetic field was applied on the MQW Laser in order to investigate the intensity of laser beam and the beam cross sectional. Analyses were pursued using Matlab package on the recorded images of the laser spot carried out using the digital camera. The results indicated that 20% increment in the intensity and 30% decrement in the cross sectional of the laser beam due to applied magnetic field of intensity 2.4 Tesla, in accordance with the original properties of the laser without magnetic field. These results could be properly used for remote sensing of the any sudden change in the environmental conditions of electrical high power stations and nuclear reactors.
