if you want my opinion, it currently is the most "BASIC" of lasers.....8200-8500 temp ya know
btw, i have helped someone else with their laser, and my methods are the same so it wont be that original....
oh god.......why?!! so first of all the middle two phot arent heated becuz nothing hot touches them, and the phot on the outside dont seem to be working.....so you can make it 2 thick or ....that will probably be the most good (lol at my grammar) thing to do.....IF you want all phot to be heated doesn't really matter beside the fact that when they hit the wall gets hot then cooled by the middle phot.....
