Components player expands VCSEL range

Laser Components has expanded its range of VCSEL lasers to include emitters with 850nm and 940nm in power classes between 200mW and 50W.

All products are characterised by extremely short rise times and thus support pulse trains in the low nanosecond range and below. 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 collimated.
