Q-Switch

- These are transverse Pockels devices and the voltage increases linearly with wavelength for a given aspect ratio.

- BBO is slightly hygroscopic while RTP is not, so hermetically sealed housing is not required.

- Water cooled BBO Q switches are tested for average powers up to 150W, and RTP may be usable up to these levels at 1064nm.

- BBO optical bandwidth is 200nm to 2000nm while that of RTP is 500nm to 2500nm.
