Ule cavity heating
WebThe CTE of ULE glass is measured by a non-destructive ultrasonic test method. material is a perfect choice for various applications in space and astronomy. It is also used in … WebThe ULE cavity exhibits excellent short-term stability for laser linewidth narrowing, and long-term stability compared with the traditional Fabry–Pérot cavity. However, the long-term drift of the ULE cavity will ascribe to aging and the presence of slow temperature fluctuations. Typically, resonant frequency drift rates range from mHz up to ...
