Hi, I'm looking to trade this old style dilda for PHR 805 or LPC-826 diodes. I would like to get two diodes out of this trade so two reds or two blurays or one of both would do. The laser has seen some use but is in good shape, just normal signs of wear, i.e. no major blemishes. The laser did...

Looks like your going to have to buy a new one. Sorry for your loss, but green's aren't really meant to be taken apart, or shaken, or dropped, etc.

^and momentum is conserved, the craft blasting lasers out the back is propelled in the opposite direction of the motion of the photon ...like recoil from a rifle, the photons being the bullets in this analogy

The particle/wave duality you're talking about holds for both photons and other things that do have mass. De broglie came up with the equation lambda = h/p, where lambda is the wavelength in meters and h and p are planks constant and the particle momentum respectively. Basically it says that all...

Thanks guys ;), pen hosts are awesome you can get a lot of power in a very unassuming package... @ghostchrome, the ghostdrive is great, will definitely be picking up a few more...what is the difference between v1 and v2?

Pretty short, after about 30 seconds it gets a bit warm so I'm going to observe 30 seconds as a reasonable duty cycle. You can't really see it in the picture on this post but there is a little piece of aluminum on the back of the ghostdrive in an attempt to supply some heatsinking. As this...

I recently picked up a couple of gold pen hosts from Daguin's paypal replenishing sale and decided to do a lowered powered 445 build suitable for pocket carrying. The diode is an m-140 from DTR and the driver is a ghostdrive from lazorlabs set at 501 mA. Since these hosts have a hole above...

Is it a PHR 803, or an 805? It was my understanding that the 805 could take a little more current, around the 140 mA range?

@TJ, yeaaaaaaaaaaaaaaaaap.

@nexbox360, I bought a 532 module from you, had it in about 3 days and it exceeded my expectations. However, the previous posters are correct, $160 for 800 mW cannot compete with what's already available, and from a highly reputable source at that. You should probably stick to selling the green...

Picked up a PHR-805 diode from Cajun Lasers for just $9.99 along with some other stuff that I needed so I decided to do a quick 405 pen build. Once again, clif is top notch when it comes to getting things out in a hurry and the customer service is second to none, even got some goodies with my...

Thanks Sigurthr and everyone else for your input. I still have to shrink wrap the connections but it's alive!!! ;)

@jmillerdoc Very kind gesture on your part and a great deal for the winner...less than $0.50 per mW...

Ok, so I bought some green and blue 2.0 mm diffused LEDs and I think I'm gonna go with the green. Thanks for the resistor calculation Le Quack ;)

Thanks! Ill post here with the results when I get time to put it together, now the question is which color LED best suits a 445....

I'm working on a 445 build and I want to incorporate an LED into the build so that when the laser is powered on the LED also lights up. I'm using one of the ghostdrives at 501 mA. The setup is pictured below. Any ideas? PS: I had a few drinks while I was soldering this up so be kind...;)

Re: 150-200mw green 532nm 3v module LPM Results included shipped in/from USA OUT OF S I put the module in one of a couple of empty E3 hosts I had lying around , decent heat sinking ability with these hosts as they are mostly 1 solid piece of Al.
