Spot Cooling for Industrial Lasers & Optics

A focused laser beam can generate a significant amount of heat. High-power industrial lasers can generate in excess of 10,000 Watts during operation of thick metals.

Temperature control of the sensitive optics inside the laser needs to be maintained to achieve peak performance.

Changes in temperature can distort the laser wavelength as it passes thru the optics, causing inefficiencies that can result in poor welds or sputtering.

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.

This application note will focus on how thermoelectric coolers can be used for spot cooling of industrial laser optics.
