WebThe exit window of CO2 laser systems conventionally consists of ZnSe. At high-power levels, however, the residual absorption of ZnSe results in the formation of a thermal lens which strongly affects the beam quality and the position of the laser focus. In this context CVD diamond laser windows have gained significant importance. A heat spreader transfers energy as heat from a hotter source to a colder heat sink or heat exchanger. There are two thermodynamic types, passive and active. The most common sort of passive heat spreader is a plate or block of material having high thermal conductivity, such as copper, aluminum, or diamond. An active heat spreader speeds up heat transfer with expenditure of energy as w…
