Pulsed tunable solid state laser
Patent
·
OSTI ID:7006056
This patent describes an apparatus. It comprises a solid state laser medium, coupled with an energy source, for amplifying a beam of coherent radiation along an optical path; a beam expander mounted along the optical path, having a first side facing the laser medium and a second side, for expanding the beam incident at the first side and transmitted out the second side in a first direction perpendicular to the optical path and for focusing a beam incident at the second side and transmitted out the first side; a grating, mounted along the optical path facing the second side of the beam expander at an adjustable angle of incidence for reflecting the expanded beam incident on the grating, the grooves in the grating being essentially perpendicular to the first direction and to the optical path; and means, connected to the grating, for adjusting the adjustable angle of incidence.
