The HighLight DL HPR Series from Coherent Inc are Fiber Coupled Diode Lasers that operate at 940, 980 and 1020 nm with a tolerance of +/-10. These lasers can deliver a CW output power from 1000 to 4000 watts with a power stability of ±2%. They have a laser On-signal frequency of 1000 Hz and exhibit an analog modulation of 600 Hz. The lasers operate over an AC supply voltage of 230 to 400 V with a maximum current consumption of up to 20 A. These devices also have customer interfaces for Analogue Power Control (0-10V DC), a digital power control (24V DC), and can be controlled via an Ethernet. With their standard, 19” rack mount form factor and integrated electronics, these lasers are easy to incorporate into existing systems and are well-suited for the space-constrained environments often found in automotive manufacturing and semiconductor fabrication.

These lasers provide a homogenous beam profile with QBH and QD interfaces and use conduction-cooled diodes that do not require deionized cooling water. They have a 45% wall-plug efficiency that minimizes the energy consumption and cost of ownership. These diode lasers are available in a rack-mount unit that measures 652 x 483 x 267 mm and offers unmatched convenience and economy for metal processing applications such as cladding, heat treating, and brazing. These devices come in both turn-key and customized OEM configurations along with an extensive range of options that provide the flexibility for integration into a wide variety of laser-based manufacturing systems.
