There is a very strong interest to achieve stability from mode-locked laser beam for satellite laser radar station at Helwan by using a more simple, stable, and easier mode-locker. The energy stability of the laser output can improve the accuracy and reliability of the Helwan satellite laser ranging station ranging data remarkably. Normally, the saturable absorber dyes dissolved in dichlorethan has been used for Q-switching and Mode-locking of this system for many years. Decomposition and degradation of this type of mode-locking is a disadvantage simply because it is not permanent and needs...
