They take as long as they take. I have a green pen pointer that acts similarly. It runs 5-7mw until you play with it for a few minutes, then it'll *pop* to 27mw. It just depends on the crystals, and what temp they want to run at to get in the mode with the most power. From the pics i've seen of these particular lasers, the TEC just cools the diode, not temperature stabilize the crystal pair. But someone correct me if i'm wrong on that. I'm only going by pics after all.
Like I said before. These are cheap chinese lasers. That means they're made of the lowest cost parts the manufacturer could find. This doesn't always mean it's substandard quality, but it does guarantee it's not going to be of the highest quality though. My guess is these are sold as 150mw because this is a rare case of someone being honest, and going by the lowest common denominator, power wise, instead of the highest. Otherwise they'd be listed as 350mw lasers.
And there's pics of one opened in this thread:

Good deal that was what I was looking for. I have not had much experience with DPSS and thought the rise or fall would be more linear.
I did see those pictures. I guess I will tear it open when I get home. Maybe my pot just needs a little finesse to see 350-400mW.
