Laser Oscillator,of two basic components: an optical amplifier, and an optical resonator. The optical resonator, comprised of two opposing plane-parallel or curved mirrors at right angles to the axis of the active material, performs the function of a highly selective feedback element by coupling back in phase a port

Q-Switches and External Switching Devices,the power and temporal characteristic of the beam obtained from a laser oscillator. Other switches employed outside the resonator include optical gates, which are used to select one pulse from a train of pulses or to slice a small portion from a larger pulse, and optical isolators, which are employe

Mode Locking,f the required pulse buildup time. With the pulse-transmission technique, the pulse width can be reduced to a minimum of 1 to 2 ns. The limitation here is the length of the cavity, which determines the pulse length. Ultrashort pulses with pulse widths in the picosecond regime are obtained from solid
