Laser Components has enlarged its vertical-cavity surface-emitting laser (VCSEL) product line to include emitters with 850 nm and 940 nm in power classes between 200 mW and 50 W. In VCSELs, light is emitted perpendicular to the chip’s surface and can therefore be easily collimated. The compact multimode lasers’ high power and short pulse sequences ensure extended range and higher resolution and make them suitable for lidar applications, among others. The products are characterized by extremely short rise times and thus support pulse trains in the low nanosecond range and below. The semiconductor structure enables the emission wavelength to remain nearly constant, even with temperature fluctuations. That allows narrow bandpass filters to be used on the detector side. The laser diodes are also available as powerful arrays.
