In Photography SE I've just asked LIDAR burnout; ways to check for damaging infrared lasers before shooting besides looking for posted warnings? and discussed a camera that was damaged by a self-driving car's LIDAR system at the recent CES show.
The article linked there mentions the powerful "fiber laser" used by that car's LIDAR system. For those I normally think of infrared wavelengths around 1500 or 1600 nm used in communications, but for simple semiconductor lasers based on III-V material the wavelengths are often around 800 or 900 nm.
This is just from personal memory. I'm wondering if I've got it right, and/or if there are other sources for common laser wavelengths used in obstacle detection and ranging.
