01 / Product introduction

Product introduction

This 905 nm six-junction pulsed laser chip uses six vertically stacked active regions with a tunnel-junction structure, reaching 240 W of peak pulse power from a very small emitting area. Exceptional optical power density, nanosecond response, high conversion efficiency and high-temperature stability make it the core source for long-range automotive ToF LiDAR and high-end industrial sensing systems.

02 / Core application scenarios

Core application scenarios

01
Automotive and autonomous-driving LiDARPrimary automotive radar, mid-to-long-range time-of-flight (ToF) LiDAR and high-speed obstacle avoidance for autonomous driving.
02
UAV and robot perceptionHigh-end UAV radar ranging, industrial AGV/AMR autonomous navigation and high-precision 3D spatial modelling.
03
Industrial ranging and securityVery-long-range handheld and fixed laser rangefinders, perimeter security monitoring and high-precision industrial control.

03 / Core advantages

Core advantages

01
Six-junction power step-upSix vertically stacked active regions push single-chip peak pulse power to 240 W, substantially extending LiDAR detection range and penetration.
02
Very high emitting power densityExceptional power density from a small emitting window reduces spot overlap and shrinks the optical system.
03
Ultra-narrow 5 ns pulses5 ns pulses at 0.01% duty cycle give very fast response and higher range resolution and measurement accuracy.
04
Beam geometry matched to micro-opticsControlled divergence of 22° fast axis and 8° slow axis with an even output spot pairs readily with micro-lens collimation and shaping.
