Thank you sir. 50c

I'm not talking about an exact temperature. I'm talking about a general threshold. I'm making precision heat sinking. I guess I'll spend the money on a diode to blow out. I'll let you guys know.

I'm talking about the temperature of the outside of the diode. I know that the temperature of the chip is going to be greater than the outside temperature, but there must be some threshold of max temperature that can be taken from the outside of the diode.

I am looking for the general failure temperature of blue diodes like m140, 9mm, and osram diodes. I have a digital probe thermometer that will be used to determine the efficiency of my heat sink cooling system, but I need to know the temperature limit I should avoid first. Does anyone know the...

I would agree DPSS would be more inclined to sensitivity. As far as diodes, like the m140, would the "filaments" (proper term?) of the laser chip be prone to degredation under vibration while at max output? http://users.telenet.be/nihao/Laser/Macro/Macrodiode-5.jpg

Simple question. Are laser diodes sensitive to vibration? Say I drop said laser, mounted in a housing, on the ground. Can this damage the delicate insides of the laser diode? Second, say I have a cell phone vibration motor installed into said laser (for interesting beam effect). Will this...

Even better. Lets stand right next to it with it pointed up at our faces.

They are wearing clear goggles as eye protection against a visible light laser.

Ideally the heat sink is made with a material that has the highest specific heat. So I am still convinced that a tight fitting low profile water reservoir is a realistic idea. Table of Specific Heats

good to know

The challenge is half of the fun. So you haven't seen a compact water cooled system before in this community?

Streamlined and ergonomic are criteria to my design (This is why I was looking into alternative heat sinking). Thus bulky heat sinking is something I want to avoid. I am looking at your Gex host at the moment. It is a clean design. I'm tempted. Though I really just want to go out of my way to...

There is a beautiful infrared laser display in ZERO DARK THIRTY during a night vision scene.

Ah. I see. 20% efficiency is quite a blow. No doubt I will still toy with the idea. I have another idea to use a water filled copper reservoir that fits snugly around the module and driver. Then heat sinking the reservoir. Or instead of heat sinking the reservoir I plan making the reservoir...

I have been looking around online for a graph of the waste heat output rate (waste power) over the amperage input for the m140. I want to build a micro peltier cooling system that will give the most efficient compact cooling for a nonstop duty cycle. What I need to know is at what rate do I...
