一种新型近红外脉冲强光辐射源的探索

Study on a New Type of Strong Pulsed IR Source

探索了一种产生近红外脉冲强光辐射的新途径。用冲击大电流使铜丝爆炸产生圆柱式内爆冲击波 ,冲击压缩惰性气体 ,产生等离子体辐射近红外脉冲强光。实验表明 ,用这种方法已经得到了总功率为MW量级 ,脉宽为 1 0

A new approach producing strong pulsed IR is studied theoretically and experimentally. Cylindrically imploding shock waves have been generated by use of strong impulse current making thin copper wires explode. Cylindrically imploding shock waves can make Argon ionized produce plasma and excite strong pulsed IR. The study indicates that strong pulsed IR of MW power and 10μs FWHM can be gained by using this approach.
