How to increase laser of the GD-rom?

[Michal]

Thanks but i know which would be the consequences.
I have to increase the laser of my dc cause it don t want to read my games...sometimes it reads and sometimes not...this dc was given me from a friend of mine and I am trying to make it working.
So...can you tell me how to increase the laser a bit more? I only want to try if it will solve the not read problem.
Thanks.
