What is a cryogenic laser
What is a “cryogenic laser”? In fact, it is a laser that needs low temperature operation in the gain medium. The concept of lasers operating at low temperatures is not new: the second laser in history was cryogenic. Initially, the concept was difficult to achieve room temperature operation, and ...Read More -
