specific Embodiment approach
[0011] The specific embodiment of the present invention is as follows: After the input power supply AC220V / 50Hz passes through the AC-DC conversion circuit, it supplies the single-chip microcomputer control circuit, the working laser driving circuit 0, and the working laser driving circuit 1 with regulated DC power respectively. The working laser driving circuit 1 is a negative feedback control circuit using the driving current as the sampling signal, and the amplitude and output mode of the output current are all controlled by the single-chip microcomputer control circuit. The driving current output by the working laser driving circuit 0 and the working laser driving circuit 1 is the energy for exciting the laser inside the corresponding working laser. There is a precise optical path design inside the semiconductor laser component, and finally the beams of two working lasers and one aiming laser are coupled into the same optical fiber. Both the working laser and the aiming las...

The invention provides a multifunctional semiconductor laser dental therapeutic instrument with dual-wavelength working lasers and relates to the technical field of semiconductor laser medical treatment. Working laser wavelength of a universal semiconductor laser dental therapeutic instrument is in a near-infrared band and aiming laser wavelength is in a visible light red band. Working lasers andaiming lasers in the prior art are both single wavelength lasers, but such a situation has a defect that single-wavelength working lasers are not completely suitable for treatment for various complexdiseases in the oral cavity because tissues in the oral cavity are complex and requirements for energy, wavelength and emission mode of semiconductor lasers are different in order to achieve the besttherapeutic effect for different diseases. The multifunctional semiconductor laser dental therapeutic instrument has dual-wavelength working lasers, can select the working lasers with one wavelength and also can superpose or alternately output and use the working lasers with two wavelengths. According to the multifunctional semiconductor laser dental therapeutic instrument with dual-wavelength working lasers provided by the invention, various choices of wavelength and emission mode of working lasers are supplied, effectiveness of treatment is enhanced and field of treatment is expanded.
