The suppression of the high frequency at the spatial beam profile is very important to develop the high power laser system. The high frequency at the laser beam is growing due to the nonlinearity of the laser medium according as the laser intensity increases, the result is that the medium is broken. The spatial filter plays an important part to remove the high frequency for the protection of the optical medium, and to gain a high energy effectively.
