Title:
LASER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/078437
Kind Code:
A1
Abstract:
As to implementing a laser, having various wavelengths, with one medium or resonator, a resonator which uses alexandrite, having a wavelength of 755 nm, as a laser medium requires heating to increase the temperature of the laser medium, whereas a resonator which uses Nd:YAG, having a wavelength of 1067 nm, as a medium requires cooling. The present invention relates to a laser generation device which has the two laser media, having different wavelength bands, mounted in one resonator and thereby enables operating on various treatment areas to which the respective wavelengths are applicable.
