HCSEL solves the three major needs of lidar for light sources

LEMON Photonics' exclusive HCSEL horizontal cavity surface emitting laser chip can meet the three major needs of laser light sources for popular lidar applications:

1. Higher peak power to achieve longer detection distance;

2. Smaller spectral temperature drift makes HCSEL have a higher signal-to-noise ratio;

3. Longer laser bands are safer for the human eye.

Blind spot detection, line scan lidar applications

Performance: HCSEL wavelength 940nm, 976nm optional, pulse peak optical power can reach hundreds of watts, nanosecond (ns) level pulse, HCSEL slow axis full angle less than 0.5° approximate parallel light, fast axis divergence angle full angle 15°, so HCSEL is a natural line light source.

With a built-in DOE-coupled output on the chip, the HCSEL frequency is stable and feedback-proof. The power increase of a single chip can be achieved simply by increasing the chip size and light output aperture. LEMON Photonics' HCSEL single-chip size can be customized in less than 1mm ~ 10mm.
