Anyone taken the time to figure this out?

I am wondering if there is a similar design aspect on green DPSS lab lasers as there is on blue and red lab lasers that would allow a person to "get more than they paid for" in effect. Clearly when a blue 445nm 1w lab laser is built it is most likely built using the same diode a, let's say, a 1.3w blue lab laser. Someone could easily change the driver current on one of the laser heads to pump more power out. I am wondering if the same thing may be the case with green 532nm lasers where something like a standard 3w or similar IR diode is used to pump a range of of power in the same green 532nm head and all the company does is change the current on the driver. Basically I am wondering if these companies sell the same basic head for a range of powers and charge more or less money for different current settings. If this was the case then someone could figure out what head gives a certain range of green powers and then buy the lowest one for the least amount of money and then change the current to the highest output for that head. Anyone out there know if this may be the case with 532nm green lab lasers? I realize there is more than just cranking up the current involved like proper heat sinking, TEC efficiency and settings, etc....what I am not sure of is the actual crystal set being pumped by the IR diode. I am curious if it is possible to "over power" these crystals as well. Are the crystals power sensitive too? Could a crystal set made for a 500mw green be damaged by pumping it at twice the IR power? If anyone knows of a thread discussing this I would love a link. I tried to use the search function on the forum before I posted but didn't come up with anything like what I was hoping to find. All comments welcome. Please tell me if I am way off base here or if I may be onto something.

Thanks!

Well I think I may be wrong also here but I will give it a go

Last I heard if you over-pump the crystals in a 532nm unit it will damage the crystal and make the laser completely useless. Like I said I am not 100% positive but I think it makes logical sense for such an event to happen.

You can damage the crystal by pumping in too much heat that it wasn't designed to handle or over saturate the crystal at which point it just because a piece of glass. In the 532 world with more power comes more integrated controlling circuits and active cooling, bigger crystals, cavity design you name it. Just like a small ebay pen you could probably over drive it to get a small increase in power but there is no point. You wont find a 500mW unit capable of 2W with just a driver change. They wouldn't design it to handle 2W then sell it as 500mW.
