4 kW High-Power Direct Diode Laser (DDL)

Technology Overview

4 kW High-Power Direct Diode Laser (DDL).
4 kW High-Power Direct Diode Laser (DDL).

Laser sources, the most critical component in laser-based processing equipment, account for 30% of the NT$20 billion worth of annually imported laser equipment. ITRI’s 4 kW high-power direct diode laser (DDL) is a success featuring arrayed laser diode technology with high-efficiency fiber combiners, heat dissipation design as well as driver and control power electronics. The high-power DDL also features domestic laser diodes (LDs) and a smart power management function that provides real-time power monitoring and control. When laser output drops 10%, the high-power laser source self-compensates to maintain a stable output.

Applications & Benefits

The 4 kW DDL is suitable for metal welding and surface heat treatment, which can facilitate the development of high-power laser-based processing equipment in Taiwan.
