Holographic coherence length of a pulse laser

A theoretical treatment of holographic brightness for a gaussian-shaped laser pulse permits a more rigorous consideration of holographic coherence length for single-mode (TEM(00q)) pulse laser. Three cases are treated: (1) the ideal single frequency pulse laser oscillator; (2) the pulse laser oscillator with frequency sweep; and (3) the pulse laser oscillator with frequency sweep along with the laser amplifier with frequency shift. Some interesting theoretical and experimental holographic coherence length curves are presented for a Q-switched laser oscillator and amplifier system.
