A.Optical fiber spectrometer records to measure the discharge voltage xenon lamp emission spectrum

 Two. Current transformer and the pin photodetector to measure the discharge current waveform and light discharge waveform, IN and lighting of the calculated peak current pulse width Th.

 3. Test - cavity - flat cavity peace - convex cavity injection and output energy curve, measured from 500-900 V, 50V measured one o'clock

4. In the far-field divergence angle of a certain energy (700V) measured three cavity

5 Lens compensation method for measuring flat - convex unstable resonator conjugated like the location of the point (test) when measured far-field divergence angle

6. Electro-optical Q-adjustment and operation:

  1, static - that is, the KD * P electro-optic crystal, a voltage is applied to adjust the optical resonator so that the static light.

       2, closed - voltage of 3600V is applied to the KD * P electro-optic crystal, but there is no back pressure signal, then adjust the electro-optic crystal to the purpose of closing.

       News - KD * P electro-optic crystal, a voltage is applied, but also the back pressure signal, and then adjust the trigger delay, to find the best dynamic output (laser output energy and short pulse).

 7. (500V, 600V, 700V), to do the Q-switched laser experiments, and measured the laser energy and pulse width of the three injection.

 8. Cr +4: of YAG Q-experiment, to choose between two Cr +4 crystal (T0 = 35%, the T0 = 20%) were measured laser output energy with the injection (voltage) changes, the measured level width, the measured pulse width and pulse interval.

9. Angle to achieve a better phase matching angle in the mediation of the electro-optical Q-work state frequency-doubling crystal,

10. Different base frequency energy, the measured SHG efficiency (measured pulse width)
