Ok, it seems nobody gives a good answer. Normally, the solid lasers we used are polarized. Since people usally make it work at Brewst angle that reduce the loss by refelction, the laser will be horizantally polarized. while, some other lasers may not. To my surpise, the Nitrogen laser is also partial polarized, which works without osscilater. It really depends on what you are using! |
