Saturability Algorithm of a Sub-Bandgap Laser for Triggering a Photoconductive Switch

Saturability Algorithm of a Sub-Bandgap Laser for Triggering a Photoconductive Switch

Based on the experimental comparison of a GaN photoconductive semiconductor switch (PCSS) and two GaAs PCSSs, it is proposed that PCSSs made on heavily compensated substrates without the obvious optical frequency-doubling effect possess the laser-energy saturation threshold when triggered with a sub...
