Lasers for display applications
We are developing diode laser technology for next-generation displays.
Our compact, frequency-stabilized diode lasers emitting in the red, green, and blue spectral range meet the requirements for such applications. They could therefore replace bulky lasers. FBH's miniaturized laser sources also score with efficiency, precisely adjustable wavelengths, tunability, high coherence, and many other advantages. Thanks to their compact dimensions, the associated systems are significantly smaller, more flexible, and can also be used in mobile applications.

Direct-emitting diode lasers in the red and orange spectral range
When red-emitting LEDs were first used in displays, the central wavelength was around 640 nm. However, this emission wavelength is not visible to people with red–green color blindness. LED display manufacturers have therefore adapted the central wavelength to 620 nm, rendering this wavelength also interesting for laser display applications.
Systems for industrial applications require light sources with high luminance in the red, green, and blue spectral range. The sensitivity of the human eye is maximal for green and drops sharply for red and blue. Hence, there is also an interest in switching from red-emitting diode lasers to orange emission for industrial applications.
Diode laser-based laser modules from the yellow to the blue spectral range
The color space visible to the human eye cannot be completely reproduced with the three primary colors red, green, and blue. Yellow laser light can be used to cover a larger area of the color space and improve color reproduction. Tailor-made miniaturized laser modules that emit within an enlarged color space enable extremely true-color displays.
