What is a Laser Etalon?
A laser etalon is a device that is used to accurately measure the frequency of a laser beam. It works by using the principle of interference, which occurs when two waves meet and either reinforce or cancel each other out.
What does HR and OC Mirror Mean?
Both HR and OC mirrors are essential components in the operation of a laser. The HR mirror reflects the laser beam back into the cavity, where it is amplified by the laser medium and passed through the OC mirror. The OC mirror then allows a portion of the amplified laser beam to exit the cavity, producing the desired laser output.
