SOLID STATE SURGICAL LASER INSTALLATION FOR PRECISION TISSUE DISSECTION Russian patent published in 2019 - IPC A61B18/20 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. Proposed device comprises two solid-state laser emitters, the first one having wavelength of 2.7–3.0 mcm, which coincides with absorption maximum in water, and the second one with wave length of 520–585 nm, which is located near absorption maximum in blood haemoglobin, light guide for radiation delivery, wherein the first emitter is in form of a solid-state laser with pumping by a semiconductor diode, consisting of an active element based on crystals doped with Er³⁺, Ho³⁺, Dy³⁺ or Cr²⁺ ions, second radiator is made in form of solid-state laser based on Nd³⁺ : a diode-pumped Yap laser, with active A-O Q-switched and intracavity radiation conversion in a nonlinear KTP crystal and operates at wavelength λ=540 nm. In addition, the plant comprises an active or passive acoustooptical gate connected to a generator of sinusoidal voltages for Q-switching, a system of input of yellow-green, three-micron and pilot red radiation into optical fiber.

EFFECT: disclosed is a solid-state surgical laser apparatus for precision incision of tissues.
