Patent ID: 7264409

Claim:
A container assembly for a laser diode module in which a temperature control device is not incorporated in advance, comprising: a heat-insulative casing, adapted to accommodate the laser diode module; a temperature detector, accommodated in the casing; a thermal coupling member, accommodated in the casing so as to thermally couple the laser diode module and the temperature detector; a heat-conductive plate member, attached to the casing; a heat transfer element, interposed between the thermal coupling member and the plate member so as to allow heat transfer therebetween; a sealing member, disposed between the casing and the plate member so as to seal the heat transfer element; a heat transfer controller, causing the heat transfer element to control the heat transfer in accordance with a temperature of the thermal coupling member which is detected by the temperature detector; and an optical fiber, adapted to lead light emitted from the laser diode module; and a board, on which the laser diode module is mounted, wherein the casing is formed with a first opening closed by the optical fiber, a second opening closed by the board, and a third opening adapted to receive the heat transfer element and closed by the sealing member and the plate member.
