Modifying a Laser Devices pistol-mounted laser

[Aixsyd]

Hey guys,

Just curious if its possible to modify the internals of devices such as the two below for much higher output. I believe they are standard <5MW lasers, and I'd be looking for the 75-200MW range. I just bought these two weapon-lasers and don't have them in my posession yet, but just curious if anyone has ever tried with similar.

Thanks in advance!
