All-In-One, Industrial Diode Laser

The Coherent HighLightTM DL HPS lasers are high power, fiber delivered industrial diode laser systems with integrated water/air chiller that offers unmatched convenience and economy for metal processing applications such as cladding, heat treating, brazing and welding. Also, the HighLightTM DL HPS series uses conduction-cooled diodes which do not require deionized cooling water. Finally, its very high wall plug efficiency minimizes energy consumption and cost of ownership.

HighLight DL HPS Series

The HighLightTM DL HPS series is available with an extensive range of options which provide the flexibility for integration into a wide variety of laser-based manufacturing systems.

Features & benefits


CheckHeat treatment



Coherent has expanded the HighLight Diode Laser portfolio with a turnkey laser capable of delivering output powers up to 4000 W. The new HighLight HPS Series employs a modular architecture, which allows customers and system integrators the choice of lasers with various beam qualities and turn-key operation. The modular architecture combined with our service training and qualification program enables OEM customers to provide direct service for their end customers. All power levels are available with a range of output delivery fiber and optics optimized for cladding, heat treatment, brazing and welding.

The HPS System is a platform in which rack type diode lasers such as the HPR diode lasers are integrated in combination with a water/air chiller. The wavelengths between 920 nm and 1100 nm achieve high absorption in many materials and are especially suitable for processing various type of metals.

The lasers are equipped with the Diode Laser Control Unit (DLC), which offers numerous monitoring tasks and e-service capability.

Due to the unique cooling concept, clean distilled water can be used (see specifications). No deionized water is used.
