Home / Do blue laser diodes transmit light and are they usable
The blue laser is a device that emits a light beam in the wavelength range between 400 nm and 500 nm, visible as violet or blue to the human eye. Note that even lasers clearly emitting in the violet spectral region (below ≈ 450 nm) are often called blue lasers instead of violet lasers. Gallium nitride (GaN) phosphor-converted white light-emitting diodes (Pc-WLEDs) are emerging as an indispensable solid-state lighting (SSL) source for next-generation display. "The new blue laser diode represents a significant advancement in blue laser technology, providing our customers with a powerful and efficient solution for their high-demand applications," said Michael Mayr, Product Manager at ams OSRAM.
Moreover, and unlike fluorescent lamps, they do not contain mercury. Red and green light-emitting diodes have been with us for almost half a century, but blue light was needed to really revolutionize
