Small Porro Prism
CLASER develops a Small Porro prism for small laser cavity application. It is very good to use this stretched turning prism to replace turning mirror, which can easily be mounted onto a resonant spring device or a simple DC motor to provide a mechanical Q-switching function in the laser cavity. Because our stretched turning prism has its advantage compare to turning mirror:
◆ Simple to use;
◆ Easy to align;
◆ Long lifetime of operation.
