Modular laser package system

A modular laser package system comprising:

• a laser package comprising a substantially cylindrical laser-fiber housing, a semiconductor laser optically coupled to an end of an optical fiber within the laser-fiber housing, and electrical leads electrically coupled to the laser and extending from a face of the laser-fiber housing;
• a circuit board mounting platform defining a slot region and including contacts, wherein the contacts include at least a first group of the contacts electrically coupled to the electrical leads;
• a plurality of pins electrically coupled to at least a second group of contacts and extending laterally from opposing sides of the circuit board mounting platform;
• a thermally conductive laser housing mount receiving the laser-fiber housing in a slip fit and mounted within the slot region of the circuit board mounting platform;
• a temperature control device mounted to the laser housing mount to control the temperature of the laser package;
• and
• wherein the laser package, the circuit board mounting platform, the pins, the laser housing mount and the temperature control device are oriented and dimensioned to be compatible with a circuit board designed for a butterfly type laser package.
