Passive Q-Switching is preferred for simplicity of manufacturing and operation, low cost, and reduced system size and weight. CA4+: YAG (Y3AI5O12) crystals are excellent for passive Q-Switching diode pumped or lamp-pumped Nd: YAG, Nd: YLF, Yb: YAG or other Nd and Yb doped lasers at wavelengths from 1.0 to 1.2mm. Because they are chemically stable, durable, UV resistant, have good thermal conductivity, have a high damage threshold (>500mW/cm2) and ease of operation, they will replace traditional materials such as LiF, organic dye and color centers.
