Fiber optic technology has essentially replaced copper wire in datacom and telecommunication industries. Emerging applications, including artificial intelligence and machine learning, require higher data transfer speeds and bandwidth across significant distances all at a lower cost.
Used to source, detect, and control light, optoelectronics are increasingly important in a wide range of automotive, telecom, and industrial applications. With high beam quality and low energy consumption, optoelectronics offer superior performance at a low cost. Due to the potentially high-temperature environments in which these optoelectronic components operate, active thermoelectric coolers are used for temperature stabilization to ensure maximum performance and long-life operation.
Within industrial processing, laser diodes are bundled together to form a high-power laser that can cut thru materials. Laser diodes are also used in light detection and ranging (LiDAR) technology used, for example, to map the area surrounding an autonomous vehicle.
For all these packages Laird Thermal Systems manufactures several different series of thermoelectric coolers:
The OptoTEC™ OTX/HTX Series miniature thermoelectric cooler. Designed for lower current and lower heat-pumping applications, the OptoTEC™ OTX/HTX Series Series keeps the laser diode operating temperature stable at around 25+/-0.5°C, achieving a temperature accuracy of ±0.01°C.
Laird Thermal Systems designs and manufactures thermoelectric coolers which adhere to strict process control standards and pass/fail criteria, assuring our customers receive the best possible modules. Our extensive standard product portfolio covers a wide range of cooling capacities, temperature differentials, input power requirements and geometric footprints. Standard finishing options are available to accommodate alternate lead lengths, lapping thickness tolerances, and moisture protective sealants.
There are many applications of industrial lasers. Whether used for cutting, welding, micro-machining, additive manufacturing or drilling, industrial lasers generate a significant amount of heat that can affect accuracy and repeatability of the system. Efficiently cooling lasers ensures proper, long-term performance of the laser. Compressor-based refrigeration systems have long been used to cool laser systems, while thermoelectric-based chillers or coolers offer spot cooling for low power lasers and optical components.
