01 / Product introduction

Product introduction

This 905 nm three-junction pulsed laser chip stacks three active regions vertically, delivering roughly three times the peak optical power of a conventional single-junction chip from the same emitting area. Its high optical power density, fast response, high conversion efficiency and high-temperature stability make it a core source for automotive LiDAR, autonomous driving and precision industrial sensing.

Core advantages

01
Three-junction power densityThree vertically stacked active regions deliver 15 W peak pulse power from a single chip, extending ranging distance and penetration.
02
Nanosecond pulse operation100 ns pulses at 0.1% duty cycle provide the time resolution needed for time-of-flight ranging.
03
Compact emitter, easy couplingA 40 μm emitting width with 22° fast-axis and 8° slow-axis divergence gives an even spot, simplifying lens shaping and assembly.
04
Wide-temperature reliabilityDesigned for demanding industrial environments across −15 to +85 °C, with strong resistance to thermal roll-off and long operating life.
