tunable laser diode head

This is a thermal fixture for a SANYO DL-7360-223H laser diode. Mud it up with thermal paste along with a NCP15XH103F03RC thermistor and two 50 Ohm (1/2 watt) resistors as heaters that all get placed in their respective holes. Then mud up the gaps between the heater blocks and the central island containing the laser diode and thermistor. Mount a high NA lens on the lensholder block, slide it onto the track to collimate the LD output and then encase the whole thing in styrofoam with a window. Fi
