Abstract
A fluid-filled heat sink is positioned on the emission surface of a laser diode. The light beam emitted by the laser diode aperture will propagate though the optically transparent fluid to be transmitted through an output window of the heat sink. Heat generated by the laser diode will be transferred by the thermally conductive fluid to the heat sink housing which will radiate the heat or transfer the heat to a secondary heat sink.
Claims8
A heat sink for conducting heat from a laser diode comprising
- a housing forming a cavity surrounding the emission aperture of said laser diode,
- an output window in said housing, said light beam emitted from said emission aperture of said laser diode being transmitted through said output window,
- a fluid in the cavity of said housing, said fluid being optically transparent to said light beam emitted from said emission aperture of said laser diode, said light beam propagating from said emission aperture to said output window through said fluid, said fluid being heat conductive to remove heat generated by said laser diode.
