The laser is either on or off, to set the power you adjust the percentage of the time it is on while measuring the current going through it on a meter. The volts go through the tube then through the meter to ground, that way you have very few volts at the meter.

The coolant pump supplied is naff and the tube seems to have a capacity to heat Olympic size pools with ease. This persuades you towards the CW-3000 cooler on ebay for £230 from China. Then you discover the CW-5000 for £525 and the CW-5200 for just shy of £600. The CW-3000 can sink 50W which is just enough, the CW-5200 can sink 1.5kW
