Abstract
The invention, relates to a visible laser diode module, comprises a laser diode dice, a submount, and a heat dissipating metal block. A dice is mounted on a submount, and then exposedly mounted on a heat dissipating metal block. The heat dissipating metal block further comprises a conductive pad which is electrically insulated to the heat dissipating metal block and is used for electrically coupling to the laser diode dice.
