The measurements of laser induced emission (LIE) of a tungsten filament upon irradiation with the focused beam of a CW IR laser diode are reported. It was found that the emission occurred in visible and infrared range. The influence of the applied DC electric field significantly affected the intensity of LIE of the tungsten filament. The origin of LIE is discussed in terms of multiphoton ionization of tungsten W atoms assisted by light emission due to the intervalence charge transfer in the tungsten hybrid domain (W, W).
报道了用连续波红外激光二极管的聚焦光束照射钨丝时激光诱导发射(LIE)的测量结果。发现发射发生在可见光和红外范围内。施加的直流电场的影响显著影响了钨丝LIE的强度。从钨混合域(W,W)中的价间电荷转移引起的发光辅助的钨W原子的多光子电离方面讨论了LIE的起源。
