Default how to maintain peak power output

i have seen videos on youtube telling about how it is importent to make a laser pointer not only reach its peak power output but to maintain it, how would i go about building my own driver for the laser

Default Re: how to maintain peak power output

Building a driver that gives constant current regardless of input/battery voltage is relatively simple to do, altough many manufacturers manage to fail miserably at this.

Maintaining the peak power of a dpss (green) laser is another matter though - the cause of the power drop is mostly thermal in nature, and can only be remedied by good heatsinking of both pump diode and crystal set. To make things worse, some lasers work better when slightly warm, so overkill-heatsinking doesnt give optimum results.
