    Do 565nm - 585nm wavelengths come in Handheld Pointers?

    That would make it teal in color.

    Is Sanwulasers a scam?

    I tells ya a complete "scam". Probably more than one takin' a peak too. 😨C'mon use the search feature or peruse the forum new member before making allegations.

    Do 565nm - 585nm wavelengths come in Handheld Pointers?

    There was a member who had a handheld 556 nm laser. It was made by that well known Asian company. A subsidiary located in Texas at one time sold a pointer at that wavelength. Old thread with photos. https://laserpointerforums.com/threads/new-portable-dpss-wavelength-556nm-20mw-cni.65451/

    What happens if they confiscate your laser?

    Did you know WL started in the US?

    What happens if they confiscate your laser?

    Your confusion rests with confusing targeting aircraft, law enforcement personel with importation. They are related but separate issues. The federal law states clearly you can be fined or imprisoned or both for importing a classes 3b-4 handheld battery operated laser.... . Such lasers are...

    Panasonic develops high-power blue beam combining

    How it works (See drawing in article) The output power optimization of the high-beam-quality blue laser (its wavelength band range is 400nm – 450 nm) was realized by combining more than 100 emitters from multiple diode bars with WBC technology. This WBC technology combines the beams from... As...

    How Important Is Soft Start?

    I always start soft. One accident at work and the tour company is looking at a law suite.

    Are laser diodes durable enough to be used as light sources in prop lightsaber hilts?

    I suspect not. If I were you I'd compare pricing. I suspect leds are less expensive and certainly more rugged.

    NASA's laser zapper for Mars

    NASA is sending a new laser-toting robot to Mars. But unlike the lasers of science fiction, this one is used for studying mineralogy and chemistry from up to about 20 feet (7 meters) away. It might help scientists find signs of fossilized microbial life on the Red Planet, too...

    Popping balloons with lasers now has a legitimate military use.

    Ho hum, balloons are so last year. I want a laser that can shoot down alien space ships.

    successfully lase Pr YLF crystal

    "Only few laser materials have necessary properties for realization of lasing in visible spectral range. Trivalent praseodymium (Pr3+) is known to be an interesting laser ion for using with solid-state lasers in the visible spectral range because of its energy levels scheme, providing several...

    Diode pumped 588 nm laser

    That's not how it should read it. Output is dependent upon pump power is how it should be understood.

    Diode pumped 588 nm laser

    The laser, which uses a lithium lutetium fluoride (LiLuF4) host crystal with oxygen-free crystal growth, is an important step toward compact and affordable lasers in the green gap...

    Does laser safety goggles filter out the blue light wavelengths of LEDs?

    Unfortunately there's likely not anything you can do out in the world. Switch to warm white leds: filament bulbs are energy wasteful as you know.

    Does laser safety goggles filter out the blue light wavelengths of LEDs?

    Because such glasses are not intended to completely block all the light.

    Does laser safety goggles filter out the blue light wavelengths of LEDs?

    Since we aren't doctors go to your's. He or she can point you to a sleep clinic. Just for curiosity. Are you saying your social life is so active that you can't avoid devices that emit blue light just prior going to bed say two hours?

    Does laser safety goggles filter out the blue light wavelengths of LEDs?

    There's a possible easy solution you should have tried first. And that solution is stop using any device that you think emits blue light, such as a mobile phone, pc, tv a few hours before going to bed. This will allow melatonin to accumulate within your brain. P.S. I've read even moonlight can...

    How big is too big? Maybe this one is? Doesn't matter trinh hong phuoc will build it :)

    Looking forward to seeing what the divergence will be.
