Abstract:
A passive Q switch comprising:a first wedge of material including means for absorbing electromagnetic energy, said first wedge having a first thickness on a first end thereof, a second thickness on a second end thereof diametrically opposite said first end, a first surface connecting said first and second ends and a second surface connecting said first and second ends, said second surface being slanted relative to said first surface; and a second wedge of material including means for absorbing electromagnetic energy, said second wedge having a first thickness on a first end thereof, a second thickness on a second end thereof diametrically opposite said first end, a first surface connecting said first and second ends and a second surface connecting said first and second ends, said second surface being slanted relative to said first surface; and means for mounting said second surface of said first wedge in optical alignment with said second surface of said second wedge and in a plane parallel thereto, said means for mounting further including means for allowing said first and second wedges to translate relative to each other while maintaining a constant distant â€˜dâ€™ between said second surfaces thereof.
