A method for preventing spatial or spectral beam seeding in a Q- switched laser is described. The Q-switch trigger of the laser is delayed by several laser resonator lifetimes after the end of the pump pulse. In this way, beam seeding is completely eliminated whilst pre-lase is maintained. The method described may be used for any laser system where the fall time of the pump radiation is sufficiently fast with respect to the upper state lifetime of the laser medium.

L'invention concerne un procédé destiné à empêcher l'injection de faisceau spatial ou spectral dans un laser déclenché. Le déclencheur Q-switch du laser est retardé de plusieurs durées de vie du résonateur laser après la fin de l'impulsion de pompage. Ainsi, l'injection du faisceau est complètement éliminée alors que la pré-activité laser est maintenue. Le procédé décrit peut être utilisé pour n'importe quel système laser dans lequel le temps d'extinction du rayonnement de pompage est suffisamment rapide par rapport à la durée de vie de l'état supérieur du milieu laser.
