A lot of time on this forum I see people mistakenly posting a peak output for their laser when indeed that is more likely to be the average output. Let me explain.
Many of the cheap power meters we all use have a little thermophile sensor. This sensor take a little bit of time in order to get the lasers reading accurate. You will notice with the more expensive meters the laser output is read out almost immediately while with these meters is appears that the laser take 20 or so seconds to reach full power. This is not reflecting the lasers actual output while the meter climbs. In actuality the laser is most likely already at the peak measurement the entire time. See after you measure the laser and shut it off how the output steadily climbs down. This does not mean that your laser is slowly powering off. Get it? My suggestion is for you to measure your laser and once the peak power is reached see if it maintains that power. If it does you can safely say that your laser has an average output around there. /
