i have the same laser you have and it's not 200 mW it burns but.
do you see the <200mW the < sign means maximum 200mW if it was >200mW would mean minimum power 200 ect. ect.
plus i made this pic to show you that i removed the diode + driver and you can do the same only the grey glue is difficult to remove
plus you can damage the driver board,so be carefull removing the diode+ driverboard
( good luck )
and to help you a lilbit more i have a spare driver from the laser
( i blew 1 of those pointers myself lol )
so i will see what the max current the driver can give
so we can figuere out if you maybe can put a 250mW diode inside
( ok those will cost more then the 1 i showed you in the link )
or maybe we can upgrade it to a 300mW version if we can find a 300mW diode
