Will these components work well together? Thanks :D

Hello! Hope you guys are well. I am building a stupidly powerful laser and am wondering if these components will work well together. For the diode: Nichia NUBm44 7W laser diode. And a Astral superdrive V 5A driver. And an 18650 4.2V 3500 MAh 8A protected battery. Thanks!

you need two batteries

you need two batteries

Ah ok. In series or parallel?

 

[RedCowboy]

Series, two 18650 in series.

If you read the add it says it's a buck driver and VIN = 5-19v

Do you have laser safety glasses for 450nm ?

Astral SuperDrive V - 5A Adjustable Buck / Constant Current Driver w/ 1 kHz PWM | eBay

Astral SuperDrive V. PWM Frequency: 1kHz. Mode: Buck Driver (step-down). Ripple: Depends on ratio of V-out / V-in. At 5A and 4.5Vf output, ripple is about 1-2%. V-out (V): 2.5 - 13V (depends on current output and laser diode’s Vf).

Ok perfect

Ok perfect. Yes I do have good safety glasses for this laser project. So with all these components it all should work? Sorry new to building powerful lasers.

Yes and of course you need a copper or aluminum module to hold your laser diode and lens, you also need that lens and a host with heat
sink would be in order for a HH type form factor.

 

[ObsessingLaserDude]

Right ok. The diode I’m getting comes with the copper housing and lens and all. Thanks a TON for your help!

That copper 'housing' is great for getting heat away from the diode, but if you want run times longer than 45 seconds or so you'll need to attach the housing to something else to give the heat somewhere to go.

Right. I don’t think I’ll be using it for over 45 seconds at a time so I believe I’ll be fine. Thanks guys!
