BEST? 445nm laser driver

[smokeintheeyes]

hi can anyone tell me what the best laser driver is to power my new 2000mw 445nm laser diode up with? im looking for about 1.2watt up to 2watt. running off a 18650 pro at 2600ma or 4000ma. thank you

Hey. I recommend you tu use the FlexDrive v5 from Dr.Lava, it costs 26$. It has a max range of 1.5A and it´s a quite efficient driver, almost every one uses the v5. At 1.5A, you should get 1700mW.
Keep in mind that at those currents ( above 1W ) any driver will produce alot of heat and it´s a good idea to heatsink it, using a piece of metal and some thermal glue.
You can always use two v5 joint toguether if you dont mind spend the extra money, that way the range is almost unlimited for this diodes. Just set both drivers at 850mA and it will give 1.8A ( 2000mW ).The drivers + and - outputs are joint toguether as well as the + and - inputs. This set up is more driver friendly reducing the heat.

Up to 4 Amps??

Maybe soon we'll have a diode that can take that much, but the current 445 diodes cannot take much more than about 1.9 Amps, which is pushing them hard...

But since you mentioned it, I do have a kit using the FlexModP3 driver, that will do 4 Amps. (future proof)

hi thanks for the info. will try and get a v5 driver but there out of stock at the min. here is a link to the diode im getting. let me know what you think and if its any good. im just trying to get a nice 1.2w think that will give me about 1200mw?

Pick one up from Daguin or myself. You don't want to buy from him.:beer:

You don't want to buy from him

True dat.

 

[smokeintheeyes]

can you let me know why not to buy off David Todeschini? why are his diodes no good?

 

[anselm]

Todeschini (aka Ciphoenix) is the owner of awesome lasers.
If you click on the above link "true dat" you can read some peoples experience
with his laser shop.
If you're too lazy to read, just know this:
He is a shoddy tinkerer and doesn't take the necessary care when harvesting the diodes.
He also makes false claims in his sales and his awesome lasers website is full of fail.
If that isn't reason enough for you:
He is a disturbed individual who believes in the church of scientology and he is also
a convicted child molester.:barf:

Do you want to give money to this man?
I didn't think so either.

Those are good reasons...

Marking these diodes 2000mW is bad enough .. only some can reach these heights.

hi everyone thanks for all your help but i have to say i dont think its right saying things like that about David at awesome lasers he has helped me out a lot and i think hes a good person to work with. but i still have one more thing to ask is this driver any good for the L2 host as like i said b4 im just trying to get about 1watt too 1.2watt out of the diode.

ps jayrob i have just lost my job and it will be 2/3weeks b4 i can get the heatsink off you if thats ok? thanks for your help
