title: Time-resolved beam structure of an active Q-switched ruby laser.
abstract: Time-resolved observations show that the near field and far field patterns of an active Q-switched ruby laser remain almost constant for the duration of the output pulse. This is in marked contrast to the reported behavior of a passive Q-switched laser.
