Laser Diodes Revolutionise Optical Sensing & Material Processing
Laser diodes are highly compact and energy efficient semiconductor technologies, which are available at unit prices below $1 for mass produced devices. Products are offered in a variety of wavelengths from ultraviolet to long-wave infrared: the central wavelength is determined by the device structure and constituent semiconductor materials. Laser diodes differ greatly from light-emitting diodes (LEDs) by exhibiting a narrow spectral linewidth (monochromatic), coherent beam properties, high radiance (brightness) and superior efficiency. The figure below illustrates the addressable market for laser diodes.

The power output delivered by a single emitter can range from milliwatt to multi-watt levels. Individual emitters can be used alone, combined into laser diode bars for the optical pumping of solid-state lasers, or integrated into laser diode modules for a diverse range of applications. The figure below shows examples of end user industries that benefit from laser diode technologies for 3D sensing and imaging. The wide adoption of laser diodes will revolutionise the automotive and electronics industries.

During the past three decades, the average power of laser diodes has increased exponentially, while their average price has decreased exponentially. These incredible advances in semiconductor laser technology enable the development of sub-kilowatt direct diode lasers (DDLs) and multi-kilowatt high-power direct diode lasers (HPDDLs). Dramatic improvements in beam quality have revealed DDLs as important tools for processing metals in addition to plastics and composites. DDLs and HPDDLs are emerging as major global trends in industrial manufacturing. Recent innovations include the development of blue diode lasers for welding and 3D printing copper.
