Currently most lidar light sources utilize 905nm pulsed laser diodes, which generally has three p-n junctions in order to achieve high peak power under short pulse. The height of the overall active region is ten times larger compared with conventional edge-emitting lasers. The traditional fast-axis collimation lenses cannot achieve desired divergence angle.
Specially desired for 905nm pulsed laser diodes, Focuslight’s new FAC1500/FAC3000 series have large BFL which is not only suitable for bare laser diodes, but also compatible with diode lasers in SMT package such as TO-can and QFN. Besides, the lens length can be customized depending on the number of channels of the laser diodes (e.g. single, 4 or 8 channels).
These new lenses are an upgrade of the popular fiber rod lens solutions. The FAC1500/FAC3000 will provide improved laser energy efficiency and achieve longer detection range, and meanwhile significantly increases detection resolution and detection range, and an overall enhancement of lidar system competitiveness.
