Welding with High Power Diode Lasers
Laser welding with CO2, fiber and various types of solidstate lasers is a well established process currently utilized in a wide range of industries and applications. However, recent technological developments in high power diode laser technology have expanded the capabilities of laser welding, as well as changed its cost characteristics. As a result, diode lasers are poised to replace tradition...
متن کاملAdvanced Concepts of using diode lasers in materials processing
In the last few years impressive advances in the development of high-power diode lasers (HPDL ́s) and their production technology have been achieved /1/. Output powers in the range up to 120 W out of one 10 mm diode laser bar have been reported /2,8/ as well as rapidly declining prices. In the past most activities concerning application of HPDL ́s have been focused on the pumping of solid-state l...
متن کاملHigh Reliability of High Power and High Brightness Diode Lasers
We report on continued progress in the development of high power and high brightness single emitter laser diodes from 790 nm to 980 nm for reliable use in industrial and pumping applications. High performance has been demonstrated in nLIGHT’s diode laser technology in this spectral range with corresponding peak electrical-to-optical power conversion efficiency of ~65%. These pumps have been inc...
متن کاملWelding and Soldering with High Power Diode Lasers
The wide range of available wavelengths, high brightness and increasing reliability are breaking new ground for diode lasers. Material processing with high power diode lasers in industrial manufacturing is getting more and more important. In automotive, medical device and also solar cell production they are important tools for automated production. Closed-loop temperature control by integrated ...
متن کاملHigh-Power Continuous-Wave Directly-Diode-Pumped Fiber Raman Lasers
We describe novel fiber Raman lasers pumped directly by spectrally combined high power multimode laser diodes at ∼975 nm and emitting at ∼1019 nm. With a commercial multimode graded-index fiber, we reached 20 W of laser output power with a record slope efficiency of 80%. With an in-house double-clad fiber, the beam quality improved to M = 1.9, albeit with lower output power and slope efficiency...
