I am looking to finally putting a 2W (or around this power, I know it will differ diode to diode) into a permanent hand held host, however, I am also looking to achive at least 3-5 minutes of on time before having to let it cool down.
Other then DTR's and Jayrob's build, I dont know any other sources for sizing referance, so I was wondering if there are any other builds here that can achive this runtime and keep the diode within acceptable tempertures. If so, I do wonder whats the dimentions of the heatsink.
Right now im just planning to use a 2.25" X 2.75" aluminum head with a copper slug as the module that will hold the diode. but I would like to hear some inputs of others who have either built thier own or own a 2W 445. if this will be alright for the desired runtime.
I got a few hosts around as spares and what not, but I will probably design and build a new one for this laser. (for better dissapation and convection of heat, I was originally going to use my retired 445 build with a fatter head attached to it *middle host*).
Thanks for any help and advice.
