Lasers for Sensing

Santec has optimized its high-speed and wide scanning laser technology for use in a number of sensing applications including FMCW LiDAR. Customization of scan speed, center wavelength and scanning range are also available to meet the requirements of new sensing applications and customer needs.

Model No. Center Wavelength Features
HSL-1 1.06 μm

Single Mode Tunable VCSEL at 1.06μm

Single Mode Tunable VCSEL at 1060nm


HSL-1 is based on Santec's advanced electrically pumped VCSEL (Vertical Cavity Surface Emitting Laser) technology. This is an attractive laser for sensing applications with single mode lasing, a variable scan speed and low signal noise. The HSL-1 delivers the best in-class performance in a compact package that has been designed for system integration. The laser is robust, reliable and suitable for high volume mass production.
