TRUE YELLOW LASER or not? 25+ years wait over? // Valkyrie 573 donated by Tinker Lasers

  • Handheld, yellow lasers do not exist. That is my experience after I last year tried three that were advertised to emit some shade of yellow. None of them looked yellow to me...
    In this video, I give it another try. Can I fill the yellow gap between red and green with a new laser that should emit a wavelength right between the ones I have tested to be closest to yellow?
    Is it true yellow? How powerful is it? What is its true wavelength? How does it work? Will my camera recording in RGB (red green blue) even film it right? Let's find out!

      Yep, it is a dream of laser despite its caveat of TEM01/10-mode (I've heard that some of them hit TEM00, though it is rare). I do have enough colors to make a decent laser rainbow now. The issue is that some of them - like the 593.5 nm amber one - have short duty cycles so it will be tricky to have them all lighted at once without overheating some of them. But its not impossible - maybe with a little help from some friends... Thanks for the early watch as always!

    9:10 no you don't, you just need a rotating mirror and a photographic camera.
    Make the beam move fast enough and with a long exposure shot you'll photograph a dotted/dashed line.

      That works, good idea. I wouldn't suggest a long exposure - the shorter the exposure the higher the frequency you can capture whereas the longer the exposure the more accurately you can measure leading to a trade off. But absolutely moving the laser at a consistent (preferably high) speed would allow a high frequency pulse to be detected and all relevant details measured with reasonable accuracy by a lower frequency camera. A spinning mirror would offer that (with some line length trig needed). Again, great idea. - From a random postgraduate physicist.

    This was an incredibly interesting what of conveying this thing which CANNOT be conveyed with your cameras, our screens, and the fact that all of our perceptions - and INTERPRETATIONS - of color are different!
    You managed to solve all of these, by telling us that, to your eyes, the laser most closely matched the 12 sample. And while we have no real confirmation for ourselves, you've basically narrowed the gap down to... "your credibility and our willingness to trust in you," which is quite a bit easier than... just assuming all of those other variables are somehow magically correct for each and every viewer.
    Furthermore, the spectrometer helped! And the additional complication at 5:00 was fascinating!! I love when videos are this thorough

I keep the brightness rather low as I am subject to migraines. Cranking up the brightness fully brings yellow closer to 14 for me. Monitor color balance is set to 9300K, I'll bet that matters.

But, in any event, it would sure be worth waiting for

    There's no "yellow gap" in camera. The only reason colour reproduction failed is that no tristimulus camera implements human metamerism. Every camera uses colour profile to produce realistic output but it can only do that for some subset of spectral distributions and it so happens that your camera's profile kills pure yellow.
    In principle there is nothing preventing same issue with red, green and blue since all of them are recorded as a mix.

      Aren't CMOS sensors with RGB filters, ergo non of them are passing monochromatic yellow? Most of the time yellow is non monochromatic, it is a spectrum from white light deflection, therefore red and green are "flying in" at the same time.

      It's not really a camera issue entirely, with the proper sensor it can capture any visible light color (just as their spectrometer can, just depends on the sensor though). The bigger issue is with the screen itself. Most monitors use the sRGB color space and things with nearly singular wavelength spectral distributions like lasers will resolve to colors outside this gamut. As such these colors will end up as imaginary colors in sRGB and will clamp into the gamut which will distort their hue. With a proper theoretical monitor that had perfect coverage of the entire gamut this color could be displayed properly, and in time monitors with say Rec 2020 coverage will cover most the perceptible human visual gamut anyways and won't distort colors quite so much, so this is mostly just an issue with current 90s-era non-WCG monitor color standards beyond just the sensor's ability to capture it.

      "Aren't CMOS sensors with RGB filters, ergo non of them are passing monochromatic yellow?"
      That's false. Every non-specialized image sensor has sensitivity to all wavelengths between 400 and 700 nm.
      "It's not really a camera issue entirely, with the proper sensor"
      You did not read my comment. You do not understand what I say but you also do not ask questions.
      "The bigger issue is with the screen itself."
      There is no issue with screens. Any sRGB-calibrated screen is capable of accurate colour reproduction of any correctly recorded colour within it's gamut.
      Cameras on the other hand cannot ever be calibrated except for a subset of spectral distributions. A set of spectral distributions might produce same colour for a human but it will get mapped to different colours in the camera. The characteristic which defines whether it happens or not is "metamerism".

    • @presentfactory
      @presentfactory Месяц назад +1

      @@user-yc5fq9bv3u You didn't read what I said. This yellow laser color is fundamentally outside the sRGB gamut, and therefore is impossible to display on any consumer monitor which is likely part of why it shifts to green like this. You probably do not fully understand how color works in computers if you do not think the monitor is an issue in this case.
      This has nothing to do with "metamerisms", I do not think you again understand how color works in computers. Spectral data once measured can be converted to human-recognizable colors via color-matching functions that have been measured based on human perception. All computer color is already based around these "metamerisms" and other perceptual illusions with saturation, contrast and etc (with varying degrees of accuracy depending on the model use).
      Of course, the camera is not a spectrometer so the problem may also be that indeed something with how it measures the color, but it does not really need to know what the exact spectral distribution is to know what color it is if it has a conversion to these other established color spaces. It's not going to be perfect but yeah it clearly works well enough when designed properly as cameras look quite accurate to what we see otherwise.

    From what I remember from my practical physics lasers courses, you can get yellow by using non optimal angle on the OPO (optical parametric generation) crystal . I don’t know the efficiency but it should be pretty low compared to green if you use a 1064 nm laser, but with the crazy power/price we can get nowadays maybe it would be enough to get 20mw of yellow output at a reasonable price.
    Maybe the large metal casing is to dissipate more efficiently the waste heat.
