can any laserists in the uk help

Hi, i have a qty of 1w blue laser diodes that i want to set up for an experiment. I want to be able to shine the laser beam on to a reflective mirror but it needs to run for about 20hrs without overheating the diode. It will need a on/off switch, diode driver and sufficient cooling for long periods of use, it needs to be as small as possible for me to fit the diode into a small space (about 1cm wide x 2 cm height) The diodes are from a A130 and need them to run close to 1W. Can anyone who lives in the UK help? in return for your service\parts used i will donate some diodes for your own use.
