  • 764H-061 Laser Diode Mounts

Newport CorporationRequest Info
IRVINE, Calif., July 1, 2010 — The 764H-061 laser diode mounts from Newport Corp. can handle up to 61-W thermal loads at 25 °C ambient temperature with their air-cooling system. The internal series of thermoelectric coolers enables fine wavelength tuning and good power output stabilization. For added convenience, the high-power laser diode mount family can accommodate both free-space and fiber-coupled diode laser bars.

The devices are optimized with the company’s Model 3700 high-power temperature controller to provide rapid settling time, while maintaining the required temperature regulation. The copper mounting plate supports most laser diode family products from the former Spectra Physics division, which is now part of Oclaro.

The laser diodes are attached to a top copper plate which is configured with a variety of hole patterns for easy integration and/or mounting. Custom or other laser diode hole patterns also can be created easily. A 10-kΩ thermistor sensor is embedded into the top plate for feedback loop temperature control.

Electrical connections to a temperature controller are provided via the pigtailed cable that is attached to the mount. The cable is directly compatible with temperature controller Models 3150 and 3700. Using cable Model 300-04, the laser diode mount is also compatible with the company’s Model 350B temperature controller.

Other mount features include a versatile hardware kit (post and post holders) for tabletop experiments and an included power supply for the fan.

Maximum thermoelectric cooler output current is 11 A, maximum operating voltage is 24 V, and heat dissipation capacity is 110 W. Operating temperature range is from -10 to 50 °C. The laser diode mounts measure 141 × 120 × 200 mm and weigh 3.7 kg.

power supply
Refers to the voltage and current necessary for the operation of circuit devices.
A solid-state semiconducting structure (basically one of the bolometers) that changes electrical resistance with temperature. Materially, some kind of ceramic composition is used. A thermistor has much higher electrical resistance than metallic bolometers and hence requires much higher voltages to become useful.
