Handheld 412nm Blu-ray (Violet-Emitting) Laser

[instinct]

I just got my spirograph today.. I was so excited to get it... My first Blue/Violet laser. I just wish there was a way to just get the beam, without the spirograph.

It's really cool.. I can't wait to see it at night.. I'm going to try and use it with some fog to see if I can see the beams.

BTTT: Performed spectroscopy of fluorescence of a "405nm Violet Laser Phosphor Target" when irradiated with this laser.

BTTT: Performed spectroscopy of fluorescence of the 2009 NIA Commemorative Insulator in uranated* glass when irradiated with this laser.

*"Uranated" - infused with an oxide of uranium, *NOT* pissed on.

Commonly referred to as "Vaseline glass" because it has
a distinct pale yellow-green color when not being irradiated.

Note spelling: "urAnated", not "urEnated","urInated",
"urOnated", "urUnated", or sometimes "urYnated".

Hi LED_Museum,

i'm interesting what happens if you 'cool down' the Laser with a Peltier or Cooling Spray. Maybe with measurings the Power and the Wavelengh changes.

Greetings

I have access to neither a Peltier nor "freeze spray", so this is one test for which I am simply not equipped to perform, sorry about that. :shakehead

Knowing this, I'd fully expect to see the wavelength shorten somewhat (possibly slightly but spectroscopically detectable; but possibly quite drastically though too) and the power output to increase by an unknown amount - but an increase that would most definitely show up on a laser power meter.

i just received 405nm 130mw module, that i'll use for my project, beam you can't see unless there is smoke, fog or dust in the air, at night it is visible but not as visible as 50mw green laser diode i have.

as far as i know ban on importing lasers over 5 mw applies to laser pointers only, not to parts, or modules

BTTT: Performed spectroscopy of the fluorescence of the white shirt of a SpongeBob SquarePants plush (stuffed critter) and of a white lampshade when irradiated with this laser.

I cant believe that tiny pen laser will reach almost 300mW.
do you know what kind of diode it is using? and what current?

 

[The_LED_Museum]

The system current is 231.30mA; but since there has to be a step-up converter in it, the actual laser diode current will be less - but I'm not able to measure that without destroying the product.

And I do not know what kind of diode it uses, sorry about that. :shakehead
I just evaluate 'em, I do not make 'em.

BTTT: The URL leading to this laser creator's website is no longer any good, so I yanked it out of the review.

Can this laser be purchased today, where?

Sorry, I do not know where you can find this critter or even one remotely like it at the present time. :mecry:
