Title:
MEDICAL LASER DEVICE
Document Type and Number:
Japanese Patent JP2948794
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable to use multiple wavelength for the single wavelength laser light source by allowing laser hand pieces having solid state laser excited solid state crystals in them to be used for a single laser light source.
SOLUTION: Hand pieces 201 to 205 have a joint part 21 which can be changed and detachably connected to a light guide body 2 of a semiconductor laser light source 1. The hand pieces 201 to 205 have a solid state crystal 25 in them which is excited by laser light from the laser light source 1 and generates laser light with a wavelength different from that of the laser light source 1. The hand piece 201 is provided with a condensing lens 23, R mirror 24, F mirror 26, condensing lens 27, and window 28. Handpieces 202, 203 and 204 are application versions and 205 is a version using a solid state crystal higher harmonics. They are different in their inner structure but they can be selected as necessary and connected to the guide body 2.
