VCSEL lasers powerful emitters with short rise times

Thanks to the semiconductor structure, the emission wavelength remains nearly constant, even with temperature fluctuations. This allows narrow-band bandpass filters to be used on the detector side. Upon customer request, the laser diodes are also available as powerful arrays.

In vertical-cavity surface-emitting lasers (VCSELs), light is emitted perpendicular to the chip’s surface and can therefore be easily collimated. The high power and short pulse sequence of the compact multi-mode lasers make this technology attractive for the LiDAR market, among others.

There, these properties ensure greater ranges and higher resolutions. Market researchers therefore assume that the global market for VCSEL lasers will grow rapidly in the next ten years.
