This is the main workhorse when it comes to photography and most other jobs.
Being Thermo-Electrically Cooled (TEC), it doesn't need to adhere to a strict duty-cycle like the other lasers.
This unit does take some time to warm up though.
If it's really cold, she's been known to start in the 140mw range and slowly climb.
It could take half an hour before she's giving readings of 170 and above. She'll soon peak for a few seconds and give
readings around 200mw and slowly sink back to the 150mw range. If I switch off at this point, and wait a minute or two before
firing back up, I'll soon be seeing 170mw again.
As most of my photographic work with this laser involves scene setup then
bursts of 10 minutes or so of photography, once she's warm, I generally average about 170mw from readings taken during sessions.
