After analyzing traditional image difference subtraction algorithm, based on the theory of mathematical morphology, Top-Hat operation algorithm is chosen to remove image noise and perform the task of object detection based on gray morphology theory.

A simple Nd∶YVO 4 microchip laser with a plano/plano cavity end pumped by LD is reported.

By using a continuous wave, LD end pumped Nd∶YAG laser as a model of the experiment, the noises including intensity noise, frequency noise and field distributing noise of the laser are studied.
