Polycrystalline silver halide fibers Development of CO2 laser scalpel

Communication 2000.8I. 0mm. Can be seen from Figure 8, when the input CO! Laser was 28W, the optical output power> 20W. The total optical transmission efficiency of about 60% to 70%, including both ends of the surface of the Fresnel reflection loss and coupling loss of laser cO2. Table 1 the main physical properties of silver halide optical fiber in the blue! Fort Man Cut Man! Some lamlam Fort limonene limonene limonene Cut! Wall Jue plastic basket 640c420 ℃ 100MPs20 (pan n14 ~ 16210503-05dBmc0mm (106 ... 3 Optical Fiber CO: laser transmission system of the optical fiber transmission system used in the CO, laser output power of continuous 0.5 ~ 25 (w), power adjustable; pulse power> 50W, repetition rate lkHz. laser energy with a 100 laser power measurement LP . polycrystalline silver halide fibers with diameter of 1.0mm, length L = 1.8m, fiber loss 0.4dB / m. 3.1 optical input Figure 9 (a) as part of the input optical fiber transmission system schematic, 1 cO2 laser; 2 fiber coupler part; 3 FC fiber optic connector, FC connector cores of which the inner surface of specially treated for polycrystalline silver halide fiber-specific, in addition, there is a fixed body mechanical fiber: 4 is a fluorine plastic casing; 5 for the wine container of silver crystal fiber; 6 stainless steel metal hose. in which the optical fiber coupler with a ZnSe focusing lens, the cO2 Cambodia focused laser fiber end. ZnSe lens focal length of the laser spot diameter and fiber diameter of the decision, focused laser beam after the fiber diameter is generally 0.6 to 0.7 times the diameter. The experimental prototype in the ZnSe lens focal length r = 100mm, the focused spot diameter 12 ~ 15W. Figure 9 (c) for the specific type of cavity, in which 1 germanium lens; 2 flexible metal sheathing; 3 handle. geometric dimensions 12 ~ 15W. working part of a flexible fiber metal casing protection, proper bending, optical fiber end face with germanium lens protection. This structure is suitable for implementation into the body's natural openings cO, laser treatment, such as oral, nasal and so on. Currently, the two structures are optical scalpel was animal testing. Wai 9 fiber type c (laser scalpel indicate input and output structure around 4 Conclusion silver halide polycrystalline optical fiber is a good soft-type transmission. O, the laser fiber material, the structure has been developed into two fiber-type CO2 laser transmission systems (fiber laser scalpel), and carried out animal tests, the basis for clinical application. I believe that with the development of laser medicine and improve the performance of optical scalpel, CO,[link widoczny dla zalogowanych], laser can be achieved in clinical surgery fine.
