| Abstract: | According to the characteristic of laser pulse in medical treatment,and contraposing the flashlamp-pumped system of long pulse Nd:YAG Laser,a new control circuit of pulsed-high-current-simmer system is developed,which adopts UCC3895 to control the working state of pulsed-high-current-simmer system with supplying the simmer current needed.So the Laser receives the relevant laser pulse by the working of the flashlamp-pumped system.The working principle of control circuit which uses UCC3895 as the core is expound,and validated the feasibility of this system by experimentation. |
