Temperature stabilization

For Laser Modules, Polara™ combines the functions of the heat spreader and submount (in the typical package shown), thereby increasing heat transfer efficiency and reducing manufacturing costs. With power densities approaching 10 MW/cm2 and sensitivity to temperature fluctuations, laser diodes require both heat spreading and temperature stabilization.

Polara technology is scalable to any power density. Devices with multiple emitters such as laser diode bars also require all emitters to operate at the same temperature. Unlike simple conductive heat spreaders, Polara's anisotropic design ensures isothermal operation and uniform wavelength emissions.
