It would be really cool to have a purple laser! I guess the price is like 1,200,149 USD, but do you have any information about them? _________________ 30 mW CNI Greenie! Smokes Leather, Pop balloons, Melt black plastic, Cut Black Electrical Tape, etc etc...

Technical nit-picking : Purple is a non-spectral color made by combining red light with blue or violet light. Violet is the proper term to use when describing single-wavelength lasers near 400nm, such as the Sonar. A purple laser WOULD be a very cool thing - because you could split the beam with a prism into red and blue/violet! _________________ \"Man, that thing is WAY too bright!!\" \"Yeah...and your point is...?\"

I thought the sonar was blue? I meant a really dark purple laser... _________________ 30 mW CNI Greenie! Smokes Leather, Pop balloons, Melt black plastic, Cut Black Electrical Tape, etc etc...

The sonar is violet. So violet that it's almost UV.
The 'blue' bit comes in from the fact that the laser-diodes are from Blu-Ray players.... But.... Blue they're not. They're beyond blue...

Use the correct goggles and avoid eBaysers if you value your eyesight
RS500(E) lab laser. Variable focus, variable stabilised power from <0.5mw to 500mw +/- 5mw over 4 hours !
150mW Lab-Laser.
SUB 100mW Fusion (it actually peaked at 138mW - average 90mW) !!!
~8mW green eBayser.
BluRay Sonar - Pairs of CR123A batteries consumed: 8
Pulsar 125
100mw focussable Pulsar.
5mw Atlasnova 635nm, only 2.4mw. Mis-shaped spot, lots of spray. Worst laser I ever had.
800uW red diode and a couple of HeNe lasers with PSU issues.

Yea it is very close to UV, being around 400nm: It 400nm area looks almost black in this image though... I would love to see pictures, especially ones like the cool prism work that RR does. _________________ Pseudos Divergence & Beam Diameter Calculator Sams Laser F.A.Q.

here's a better chart... As you see, the sonar wouldn't be too visible... though I do think it would be more visible than that! _________________ I'm building a JET ENGINE! check my site HERE!

The first spectrogram is an accurate representation of the visible spectrum, sunlight through a prism looks exactly the same. A laser outputting violet light would be very dim indeed.

So what color is 555nm? Half Green and Half Yellow? Nice chart, I've been trying to look for one like this. _________________ WL Fusion 125mW All-Black W/Clip 1.0252621079 mRad Match Burn: 3-4 seconds @ 1ft.

Pretty much. One would probably call it lime. Remember when they started changing US red firetrucks to lime green fire-trucks? All about visibility.

It would be cool to have a purple one..but the violet laser is even less visible than the reds. So it would take a heck of a lot of power to make it nice and bright. _________________ 125mW Fusion - Divergence- 1.0 mRad \| TEM00-TEM01* Doughnut mode \| 119mW peak, 103 Nominal 55mW CNI - Laserchecked at 65mw peak, 55mw nominal \| Divg -2.18 mRad \|MIA!

so would a blu ray laser made from chopping a player be visible (as violet) or is it so close to the invisible spectrum that u cudnt see it?

It would resemble the color of a blacklight LED, and would have low apparent brightness considering the power level. _________________ \"Man, that thing is WAY too bright!!\" \"Yeah...and your point is...?\"

You have this nice spectrogram within this thread and you still have to ask this question. Go take a look at it, it will answer your question.
