The Measuring System of Photo-Stimulated Discharge Based on the OPO Laser

摘要：

Photo-stimulated discharge (PSD) is an effective method to characterize the deep traps in the dielectric materials. In this paper, a new PSD measuring system was firstly built up based on the optical parametric oscillator laser. The laser can generate continuously tunable wavelength output light of which wavelength range is 210-420 nm and average output pulse energy is 2.3 mJ. The system overcomes the shortcoming of weak output energy in the experiments before, especially in the range of ultraviolet band. Experiments proved that this PSD system can work well and can be widely used in the theoretical and practical research of the dielectric materials.
