Laser diodes continue to find new product applications as the lasing wavelength is pushed lower into the visible spectrum. The latest generation of Visible Laser Diodes (VLD's) operate at or near 635nm; this wavelength being equivalent to a helium neon gas laser, is highly visible to the human eye. VLD's in the range from 635nm to 685nm are replacing the traditional HeNe laser in many commercial products for good reasons: lower cost, compact size, and superior long-term reliability. Another intrinsic benefit, laser diodes are generally better suited for battery operated devices and other low voltage applications.
While visible diodes are used extensively in commercial products, the near-infrared diodes are certainly not extinct. There are many applications still using lasers operating in the 780nm~850nm range as some machine vision systems and sensors are optimized for near-infrared light sources. The near-infrared diodes may not be considered as user-friendly as the VLD's; however, with the right tools, some of the inconveniences can be managed. In either case, visible or near-infrared, we stock a selection of the more popular laser diodes from several different manufacturers.
