Light a candle, or use one that is way too bright on your dog? http://laserpointerforums.com/f36/laser-type-79980.html

Re: FOR SALE ! NEW 1.8W 445nm, 1.6W 445nm & 700mw 405 nm Nice looking hosts. +1 for not being able to afford them though. :-/

I have two pairs of these and they are awesome AND look good. They list for $58, but there is a discount code for survival lasers somewhere on the forums if you do a quick search.

I have the same goggles and they are rated OD 4+ in that spectral range. As others have said, the light getting through them would still be 1-2 mW (14,000 mW laser reduced by a factor of 10,000 by the goggles). I would personally treat the laser as if you were never wearing goggles despite the...

Why would you want to? The laser isn't going to be subject to subzero temperatures, and ethylene glycol has a much lower thermal conductivity than water anyways (water is ~3x better). Thermal Conductivity Common Liquids

I wasn't aware that sound had a color?

Elektron, does this make any more sense? The first one measures the heat intensity of the laser (i.e. how much light is coming out despite what color it is). Good for high power levels. The 2nd one has to be told which color laser to measure and looks for that color light. Not as good for...

Well, I'm looking for something more custom than a pen laser. I've decided that since I like ApexProxy's 445nm so much that I want a bit of power in a 405nm. Not sure what a $100 or less budget could get me though.

I love how the WL hosts look, but there are members who can build a MUCH better quality laser at a reasonable price point.

Besides having fun, what types of practical uses would a garage enthusiast use one of these beasts for? I know in industry they are used for cutting intricate patterns, but holy cow that thing is mean.

I always thought these were just called Tesla Coils. When I was teaching 1st year chemistry lab, my students always thought I was calling it a Testicle. Geez.

This is a really neat example on youtube using microwaves. Quantum tunneling on the kitchen table - YouTube

Wow, how did my rep drop so fast? I went from +10 to -139 for a simple suggestion that several of you guys thought was a terrible suggestion. Wasn't even a malicious suggestion, albeit a careless one (that I have since removed). I guess lesson learned, but geez.

How does 405nm stack up vs 635nm as far as distance burning is concerned? I'm not sure which one had better beam specs.

Blord said in your first thread that you damaged your diode by using the wrong batteries. Did you put a new diode in, or are you trying to salvage the first one?

:huh: Seems legit to me:

What is the seller's name? I couldn't find his ebay postings based off the original link.

Ya know, you would have much better luck shrinking the apple if you put a baseball in between the laser and the apple. Too much heat and all. /Cheesy movie reference.

What are you looking to do with the laser in particular? I'm guessing you are focused on burning capability since you specify 200mW but don't care about the color. As was said earlier, blues (405nm and 445nm) are pretty cheap per mW of power.
