You can try to measure the light intensity using your smartphone. There is an app called phyphox that can get information from many of the sensors and store the data in a file. Making a reproducible setup would be your task.

Thank you for your reply.

I bought a luxmeter to measure the brightness of ordinary lamps.

My problem is whether it will withstand the brightness of a laser pointer without breaking?

I would like to get an answer from those who actually made such measurements.

I live in the frontline city of Kherson (Ukraine). All our laboratories and their specialists fled from the shelling.

The question of laser energy concentration is important. Will it damage the measuring device?

You can try to attenuate the light by simple means (sun glasses, sheets of paper) or use reflected light (white paper) and increase the signal to keep it in the range of the detector.

Thank you for your answers.

I will try them out with caution.

I have a simple "home" device:

Split Type Lux Meter GN 1050.
