Title:
OPTICAL VORTEX LASER VIBRATION METHOD AND OPTICAL VORTEX LASER VIBRATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/169578
Kind Code:
A3
Abstract:
Provided is an optical vortex laser vibration device which is capable of an increased output and can generate an optical vortex even in a wide frequency range and if the optical vortex has a quantum number which is not an integer. A laser device according to one embodiment of the present application comprises: a laser light source for generating laser light; an optical vortex generation unit for generating an energized optical vortex on the basis of the laser light generated by the laser light source; and an optical resonance unit for resonating the energized optical vortex generated by the optical vortex generation unit and dividing the energized optical vortex into signal light and idler light. Therein, it is preferable that the optical resonance unit comprises a non-linear medium and a pair of resonator mirrors sandwiching the non-linear medium, and it is preferable that the non-linear medium includes at least one among KTiOPO4, periodically polarization-reversed LiNbO3, and periodically polarization-reversed LiTaO3.
