:'( the accout of my seller of my laser was be hacked and i will not have this laser for the moment :'( so i will a a 1w for the test to see if i can make a green beam and after a will buy a 2w :)

i buy this for drive my laser eBay.ca : UNIVERSAL LASER DIODE DRIVER POWER SUPPLY 1.8WATT objet 170484692030 fin) and i find that i will have more power if is separe. is harder to align but more power so a take a guess :P

ok so i will try to find a joined crystal :)

so i will try the challange to have a good aligmente if is not perfecty this is not so bad. it just for fun and not for a show... maybe later a will buy a laser power meter if i would like have more powerfull laser but now it will be ok :) so now i have eBay.ca : HIGH POWER CUTTING BURNING...

i would try to find a joined crystal it will cost cheaper :P do you have a idea where a can find it ?

It is seperate not glued. so it will hard to aligning :S

ok tank you very much ho in same time can you help me to chose my Nd:yvo4 Nd:yvo4+ Ktp Glued Laser Crystal- 500mw LD Pumped! - eBay (item 130387974189 end time Jun-01-10 08:36:25 PDT) 2%Nd:YVO4 Laser crystal!!!!!!!!!!!!!! - eBay (item 140404375912 end time Jun-01-10 08:36:23 PDT) 2%Nd:YVO4...

ok tank you i use a heatsink of a cpu + a fan il will be enougnt ? :P

ok tank you :) and for the voltage it will be ajust by itself ?

so i can just change the lm317 by the LM305 or AMC7135 add a headsink change my resistor and it will be ok ?

ok ty HIGH POWER CUTTING BURNING LASER DIODE 808nm 2W FAC - eBay (item 180505696725 end time May-09-10 22:21:17 PDT) this is my laser but i know that a LM317 can run 5amps so he can run 2amps :P so i can drive ma laser ?

hi I would like to know what kind of driver driver a need for my 2W 808nm FAC C-mount. I already have a LM317 but i dont know if it's good ? so if is good I will change the resistance but a don't know what is the amperage for this laser ? and for my resistor how many W I will need ? tank you :)

ok so it is normal to have difficulty to see it if you dont have smoke :P i can see it but its not compared to my green :P tank you
