How about DIY Laser Housing? Answered

Hi all the Guru,

I have seen many tutorials on laser engraver/cutter/burning but seen only 1 on laser housing.

I suppose many of us have DIY CNC.
Can't we use it to make a lase housing?

Please someone post an instruct able for this.

I'm also trying.

Mostly the housing of a laser needs to act as a heat sync. Nothing to it really. Just a block of aluminum with a hole through it to hold the laser and a good amount of fins to maximize surface area to allow the heat to dissipate. So if your system can mill an aluminum block into a heat sync then your good to go.

What I didn't mention was the open can diode.

Have any suggestion for that?

No different. You got to mount the diode into or onto some sort of heat sync. You'll want the housing to match up to the outer casing of the diode as close as possible to maximize heat dissipation.

Lasers are a type of Light Emitting Diode, they use current to create coherent photons (Light waves in synch) and this diode HAS a voltage across its two electrical pins which means it is using Power from Volts times Amps. Now because only a small percentage becomes photonic light the rest is turned into HEAT and must be cooled to keep it working or fail by turning into a black like hole.

The circular metal laser diode casing is made to transfer the inside semiconductor junction heat to a mounting tubular material usually metal that can absorbe heat. Metals like Silver, Copper, Aluminum, even Steel are called a Heat SinkMetals because like a kitchen sink takes water away, the Heat Sink takes temperature away.
