Hi,If you do the brightness comparison,1 watt green is equal to about 13 watts of blue for basicly the same percieved brightness to our eyes but the blue at 13 watts will be substantially more energy, not to mention very dangerous to the eyes or anything the beam hits

Hi, Athough good answers have already been posted to your question,200-300mw 520nm is extremely bright even in daylight, while the 1 watt 520nm green is insanely bright and also considerably more of an eye hazard and there is really no reason to get a 1 watt green for general purpose visibility...

Hi, I found an article several months ago in which they used a ruby crystal that was 8.6mm long and 3mm in diameter and they pumped it with either a violet or blue laser diode and were able to achieve a deep red, low power continuous beam from the Ruby Crystal. The beam was a few milli watts but...

One thing I forgot to say is I intend on trying to pump the 120mm by 6.5mm Ruby Rod with high power blue leds and possibly also high power ultra violet as well. Apparently if enough input energy is used from the array of leds or even laser diodes, it is possible to achieve a deep red continuous...

Hi, Both of the Rods are in absolutely perfect brand new condition without a single mark of internal distortion of any kind and the mirrors are also in the same perfect condition.. The only thing I am not certain of is the chromium content or how to accurately calculate how many joules of input...

Hi, I also have a Ruby Rod which is 120mm long and 6.5mm wide and in excellent brand new condition. I took some photos of it and a few of the Dielectric 30mm wide by 10mm thick Ruby Laser mirrors which are also brand new and in excellent condition.The mirrors are HR=99% Reflective and the OC=55%...

Hi, I took some photos of my Rod and will try and post them here. The Rod has no markings or damage on it of any kind and has chromium from end to end. Its 240mm long and 15mm wide.Please tell me what your opinion of this Ruby Rod is?

I have also been gathering the parts to build a Ruby laser for close to 60 years now. I finally found a suitable high quality New rod 240mm long and 15mm in diameter with perfectly polished and parallel ends. It has also taken me several decades to find some suitable di electric mirrors that...

yes, the photos of the Ruby Rod do not work for me either, they just wont open as if they are not there

Hi, Did you ever finish your Ruby Laser? I too am and have been extremely fascinated with Ruby Lasers for many decades and I too have acquired a suitable Ruby Rod which is 240mm long and 15mm in diameter and I too am hoping to one day build a laser that actually puts out the brilliant deep red...

Why dont one of you guys make a compact knife edge array that would take the 20 or more seperate beams from one of these multiple arrays and combine them into a very tight but powerful beam that would be extremely bright and be able to be projected some distance. These arrays all seem to be...

That is not even remotely impressive. Why dont you make a real collimated 100 watt or more laser by making a proper small knife edge array using beam splitters and combiners that would combine all those seperate beams into a proper thin but very high powerful beam that you could actually shoot...

Hi, I like deep red laser diodes as well and checkout these laser diodes if you havent seen them already, and another one is the LDX-3230-660 2 watts and another is the LDX-3230-665 2 watts at R.P.M.C

The price was $940.00U.S. a diode and there is another diode coming out that will be 1.2 watt at 659nm AT $299.00 U.S.

Hi Steve,I dont understand what you are referring too by long radius and near flat,as stated elsewhere on this site,I am extremely good in the electronics and the physical construction of lasers but when it comes to all the fairly high level physics involved with lasers and Ruby Lasers...

Hi, are you guys into some high power deep red laser diodes? R.P.M.C is selling 2 watt 660nm laser diodes although they arent exactly cheap.One diode is the LDX-3230-660 at 2 Watts and the other is LDX-3230-665 at 2 watts

Hi Steve, are you absolutely positive they will work as in did you actually try the kryton mirrors in a Ruby Laser configuaration and of course are you selling any of those mirrors?

Hi, Thank you for your suggestion,however Edmunds was one of the seemingly endless companies that I have already contacted and they told me that they specifically dont make optics for Ruby lasers and he gave me a very long laundry list of companies(mainly in China) that apparently do but the...

Hi, My name is Peter Zeboroff and Iv am trying to gather all the parts need to build a Ruby Laser. So far I have the Ruby Rod which is 240mm long and 15mm in diameter but I am having a great deal of difficulty locating the Cavity Mirrors. If there is someone on here that is able to help me in...

For those who may not know, sabzh21 seems to have two of these 525nm 1.6 watt green laser diodes and he is asking $142.00 U.S.
