Laser Diodes and VCSELs are semiconductor lasers, the simplest form of Solid State Lasers. Laser diodes are commonly referred to as edge emitting laser diodes because the laser light is emitted from the edge of the substrate. The light emitt… Read More
Within the laser community, one of the most overused and often miscommunicated terms is the phrase “single mode.” This is because a laser beam when traveling through air takes up a three-dimensional volume in space similar to that of a… Read More
The output wavelength of a semiconductor laser is based on the difference in energy between the valance and conduction bands of the material (bandgap energy). Since the energy of a photon is inversely proportional to its … Read More
There are a great many factors that can increase or decrease the lifetime of a laser diode. One of the main considerations is thermal management. Mounting or heatsinking of the package is of tremendous importance because … Read More
Honestly, it depends on several factors, and there is no simple chart to cover everything. Typical diode lifetimes are in the range of 25,000 to 50,000 hours. Though, there are lifetime ratings outside this range, depending on the con… Read More
The same power supply can drive multiple laser diodes if they are connected in series, but they must never be connected in parallel. When two diodes are connected in series, they will function properly as long as the complian… Read More
