Optical resonator using a passive Q switch or other optical element with low-damage threshold |
摘要 |
An optical resonator for a power laser comprises between one of a pair of totally reflecting mirros flanking the end of a pumped active element such as a Nd:YAG crystal, a passive Q switch and between the passive Q switch and the active element, a polarizer which reflects the output transversely to the optical axis of the reflecting beams of the cavity. A phase shifter is provided between the polarizer and the approximal end of the active element. This system prevents the full output energy from impinging upon the passive Q switch so that the passive Q switch or other low-damage-threshold optical elements associated therewith do not have to take the full power.
