Control System Design of Pulsed-forsing-simmer Circuit in Medical Solid Laser

根据激光医疗所需激光脉冲的特点,针对长脉冲Nd:YAG激光器泵浦闪光灯中脉冲式强预燃系统的控制电路展开研究,采用UCC3895芯片控制预燃电路工作状态的变化,提供所需的预燃电流,从而配合其他电路得到相应的激光脉冲。文中主要阐述以UCC3895为核心的脉冲式强预燃系统控制电路的工作原理,并且根据实验,最终验证了该套系统的可行性。

According to the characteristic of laser pulse in medical treatment , and contraposing the flashlamppumped 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.
