WL Phosforce on Zaser?

[The Qube]

Hey everyone. Like the title says I wanted to know if the Phosforce from WL would fit on a Zaser? Has anyone a Phosforce and could give me the exact sizes? It would really help thanks

Call WL customer service and ask WL for the thread size and dimensions of the unit---am sure they will tell you if you tell them you nneed the info to see if it will fit on a non-WL laser.

To my knowledge i don't think any one has ever purchased a Phosforce and used it with a laser other than a WL..
On to the "Can it be done??"
Well i would think so.
I'm not sure if the extra 1.3w from a 9mm zaser would hurt the Phosforce, as the highest power laser WL sells is the 2W+..
So i would tend to think that the extra 1.3w wont hurt it, but don't trust me on that
Getting it mounted on the zaser may be your biggest problem, now sure you could tape it or maybe Velcro
To be serious you could have one of the LPF's machinists make you an adapter to go from were your lens goes to the Phosforce..

So after you read all of that,
JUST BUY A FLASHLIGHT!
Much brighter and at a fraction of the cost!

I have two related questions:

1) how does WL cause the white light to move forward in the same direction as the beam? It seems like if you shine a laser on a phosphor, the light produced bounces backward.

2) Does anyone know where to get flexible phosphor material from?

1. There's a dichro before the phosphor so the blue passes through then the other colors can't go back.

2. I don't know of any flexible phosphors but I have used remote phosphors by chromalit. I posted about it here: http://laserpointerforums.com/f65/blue-laser-light-into-white-light-87869.html#post1279219

I can't call WL because I am from Switzerland and it will cost to much.

@i73770k Its not about the light and lumens, its about to have a nice little gadget. And also to can hide it from someone. (When you go trough the customs or police asks you what this is )
Yes I also thinked to ask someone if it wont fit. I thinked of Eudamonium..

Here's what I don't get - how do they avoid there being a giant hole in the middle of the resulting flashlight beam?

This is a horrible drawing, and I don't know why I made the phosphor black, but hopefully this will explain what I'm hung up on.

Some of my led flashlight do have a blank spot dead center from the style of reflectors, but only at extremely close range. When you back off the spot goes away. I'm definitely not positive this is what's happening on the wl contraption, but just a guess.

I have flashlights that throw a mile, or flood an entire field, or a bit of both, AND can be run for way longer than a laser. I'm with the "get a flashlight" suggestion.
It's a really neat idea, but just not near as efficient as the real thing

Could be they use a phosphor coated lens that lets light through, so no spot? Hard to ell if you don't have a Phosforce in hand to look at but from the photos of the Phosforce it looks like that is how they do it--perfectly round phosphor coated lens in the middle.They talk about "patented" phosphor coating which leads me to think this may be the way, also.A Cerium doped YAG phosphor system that produces white light from blue laser light is patented by Nichia Corp of Japan.

" A practical white light source similar to this is obtainable with a unique phosphor consisting of Cerium doped YAG. (Yttrium Aluminum Garnet). In this crystal, the Cerium ion, has a strong and narrow absorption at about 460 nm in the blue, and the YAG phosphor then fluoresces with a broad yellow spectrum. So blue InGaN LEDs can be used to "pump" this phosphor, at that wavelength. Some of the blue photons escape from the phosphor, unabsorbed, and the mix with the broad yellow to give a visual white light. More phosphor concentration, absorbs more of the blue to give a warmer white color, around 2,700 to 3,000 Kelvin color Temperature, while lower phosphor concentrations give more blue residual so the color Temperature is higher, and the lumens per Watt is higher, because of the lower Stokes shift losses. Additional red phosphors need to be added to give better color rendition, but that is not needed for a flash light."

Here is a paper about 4 ways to produce white light from a blue laser which describes that system and others - http://www.winlab.rutgers.edu/~crose/capstone12/entries/SolidStateLightingwBlueLaserDiodes-Revised.pdf

The phosphor is translucent. When I shine my laser to a remote phosphor strip, white light is produced on both sides. The dichro prevents white light spilling back to the laser diode and instead reflects it to the front.

I do believe the phosforce employes a diffraction grating to "spread" the beam out a bit on the phosphor panel. A majority of the directed light is collimated by the reflector. Anything that doesn't go forward would hit that blue-pass dichro, which I guess would be there to attempt to feed the light back into the phosphor. The phosphor won't get pumped by white light, but it may scatter it forward again.

Ideally, you wouldn't want flexible material, but rather, you would want to deposit your phosphor on something you can heatsink. Otherwise, you lose the benefit of using lasers, namely the ability to control the beam precisely.
