Chillers for Semiconductor Lasers

Chillers and Heat Exchangers from BV Thermal Systems used in the Semiconductor Industry

The term Semiconductor Lasers is rather broad and encompassing because of the variety of different semiconductor lasers spanning many different applications such as:

  • Small edge-emitting laser diodes
  • External cavity diode lasers
  • Monolithic and external-cavity lower power
  • Broad Area laser diodes
  • High-power diode bars
  • High-power stacked diode bars
  • Surface emitting lasers
  • Optically pumped surface emitting external cavity
  • Quantum cascade

High-powered lasers generate substantial amounts of heat and thereby require effective and accurate cooling to prevent overheating of critical components.  It is not uncommon for lasers to produce up to 55 kw of waste heat.  Removing the waste heat prevents the wavelength from increasing which can compromise the performance of the laser.  The diode laser wavelength increases with an increase in temperature and therefore the temperature must be accurately maintained.  The self-contained BV Thermal Systems Chillers for Semiconductor Lasers lasers remove heat from laser heat-dissipating components and maintain the laser temperature to insure the high quality and life of the laser.

Designed, engineered, manufactured and thoroughly tested in the United States the recirculating chillers for semiconductor lasers are totally customizable to meet the cooling requirements for your laser.  With the largest selection of options in the industry, the Chillers for Semiconductor Lasers may be designed and manufactured to your exact requirements and specifications.

Standard features as a hot gas by-pass which allows for greater stability and thermal protection for the pump, motor and compressor are included. With simplicity in design and operation, the BV Thermal Systems Chillers for Semiconductor Lasers are designed to provide years of reliable and accurate liquid temperature control.
