A less than 200$ laser engraver. Ortur is the brand. Seems to do a nice job.

Why would that make sense? Do they state batteries included on the site. You may have a wait. Read this post. https://laserpointerforums.com/threads/sanwu-lasers-offical-thread.99833/page-19#post-1578483

I'm sure you've been outside on a bright sunny day looking around without a lasting problem. Any beam you might have easy access to pales in comparison to sunlight. I've viewed a 25W argon laser beam. I only used one eye; thank God I have two. Just joking.

He looks like a person of limited intelligence.

That would make it teal in color.

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.

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/

Did you know WL started in the US?

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...

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...

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

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

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...

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

"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...

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

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...

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.

Evidently you are.
