My father knows I like lasers and recently showed me this pamphlet a neighbor gave him. His neighbor is a few years younger than me (he's 30) and he has stage 3 skin cancer. The neighbor's cousin works for a clinic and has convinced him to come to the clinic for these laser treatments. The thing...

Just noticed this today. LZSK - 473nm 10mW Water Proof Blue Laser Pointer

Violet. And by violet I mean a color that roughly corresponds to #8000FF which is halfway in between blue #0000FF and magenta #FF00FF. I don't think a computer monitor can accurately represent the violet in 405nm but to me when I think 405nm the color I associate it with is the color in between...

I like the 589nm and 473nm Spartan lasers I have.

They're very nice... 589 is like a nice beam of sunlight. 473 looks kind of turquoise to me.

I wonder how they get those more obscure wavelengths like 488, 515, 542, 561 etc. Is it simple frequency doubling of an infrared wavelength like with the 532 and 473 lasers or is it frequency summation (I think that's what they call it) of two different infrared wavelengths like they do to get...

I've gotten to that age where I no longer want to be hip and know all the current slang words. When I had to check the urban dictionary for the definition of a blumpkin I realized I'm just a big square and would be happy staying oblivious.

I wouldn't use these color names in every day conversation with people but this is how in my head I break down colors. Primary: Red Green Blue Secondary: Cyan Magenta Yellow Tertiary: Rose (Red + Magenta) Orange (Red + Yellow) Chartreuse (Green + Yellow) Spring Green (Green + Cyan) Azure...

Does anyone have a picture comparing the beams of 635, 650 and 671 beams (like all in the same photo)? I know I've seen pictures on this forum where people have pictures comparing 445 and 473 and a 488 argon I think for blues and a homemade 515 and a 532 for greens. I would like to see how 671...

The ones I know are diode 405 (but I think a 404nm DPSS is possible) 445 650 The ones I know are DPSS 473 532 589 593.5 The ones I don't know for sure 561 (I'm guessing DPSS) 635 (I'm guessing diode) 671 (I'm guessing DPSS)

dumb question...Is it possible to get a 561m laser pointer? Or is that just a theoretical possibility as of now? I know Dragon Lasers sells a 671nm spartan laser.

Yeah I was unclear what you were trying to convey. I purchased a laser pointer on ebay that was listed as 460. To me it looked just like 445. The LaserTo website also claims to sell 460s. But their website looks crappy so I don't know if I trust them. Maybe I should have put a disclaimer...

The visible wavelengths that fit into pointers/handhelds I've seen are: 405 445 460 473 532 589 593.5 635/638/640 650 671

uh...well...a lot...less so if you want them in a laser pointer :) Green Lasers,Yellow and Blue Laser Pointers :: Dragon Lasers Laserglow Technologies - Handheld Lasers, Alignment Lasers and Lab / OEM Lasers

405 to 445...yes definite difference. My 405s have a purplish dot and a very faint beam at night that's almost invisible. My 445s are blue...not purplish at all. A really good solid electric blue...the more powerful blue ones I have clearly show a visible blue beam that is gorgeous. 445 to...
