Abstract: (1681 Views)
A numerical modeling of end-pumped zigzag slab amplifier regarding contra directional pumping and saturation features is investigated theoretically. Spatial dependent rate equation has been solved taking into consideration the pump and laser beam saturation effects at high power scale. As an advantage, gain coefficient distribution along the crystal length, absorption coefficient versus pump power and optimum crystal length are calculated. Laser parameters could have noticeable differences in contrast with analytical approaches considering slab crystal as a bulk.
Keywords: laser amplifier, zigzag slab Amplifier, finite difference method, saturation effects, optimizing.
