january 2016 - active thermal management of laser systems plays an integral role in laser performance, long term stability, and reliability.  aspen systems, inc. (marlborough, ma), the inventor of the miniature rotary compressor will be demonstrating their technology at the spie photonics west february 16 – 18, 2016 in san francisco, ca, booth #4521. 

in addition to the custom cooling solutions often developed by aspen engineers, three-off-the-shelf options ideally suited for laser manufacturers, integrators, and end users are available.  the liquid chiller module, direct refrigerant cold plate system, and a stand alone, turn-key chiller.

according to glenn deming, vice president – aspen systems, “our core technology, the rotary compressor, was developed for the military as it is ten times smaller in size than equivalent capacity compressors and extremely durable with over 80,000 hours mtbf.  we are an oem supplier for laser manufacturers and liquid chiller companies that need an extremely compact, highly reliable, cooling system.”

the liquid chiller module is a complete cooling sub-system ideal for users that need a small footprint to integrate directly into a laser or external housing and where the customer wants to implement their own controls.  the direct refrigerant cold plate system is used where the cold plate is in direct contact with the heat producing source, e.g. laser diodes and offers the highest heat transfer rates with excellent temperature control of less than 0.5? c.  all modules are customizable to optimize the active thermal management for a particular application.  “a number of our customers come to us for designing custom cooling solutions that we subsequently supply for their application,” deming added.
