Laser amplifier,raightforward system, as shown in Figure 4.1. In this scheme an amplifier is driven by an oscillator which generates an initial light pulse of moderate power and energy. In the power amplifier with a large volume of active material the pulse power can grow, in extreme cases, up to 100 times.
