Violet Laser Pointer

The 445nm blue violet laser pointer (450nm blue violet laser or 445nm blue laser) is special violet laser pointer.

It’s similar to the traditional 405nm violet laser pointer, and the color of the 445nm blue violet laser pointer is blue violet, not the real violet.

E3 Purple from wickedlasers

Just got my E3! Only took about 75 days or so to ship.
Unpacked and installed 2 Energizer Max AAA batteries. It fired up, but but wasn’t as bright as I thought it would be. Can’t see the beam in the light. At night the beam is barley visible.
Shining the laser on a wall about 10′ away gives me a dot with a series of dots circling the inner dot. This pattern is about 1″ in diameter. I think there is something wrong with the lens.
What are other E3 purple owners seeing? Is mine underpowered or out of focus?

Your expectations were different from the reality of the nature of light at 405nm wavelength. This wavelength is near the end of the visibility of the visible light spectrum, bordering with Ultra-violet at 400 nm. Human eyes have trouble focusing on light at 405 nm, making it very faintly visible, even at high power. Even at 400mW you will not be able to see the beam in the light, let alone at less than 200mW with your E3. The series of dots around the dot are due to the difficulty of humans to process light of this color. Your laser seems to be working as it should.

Violet Laser Poiter from BeamQ

Lasers emitting a violet light beam at 405 nm may be constructed with GaN (gallium nitride) semiconductors. This is close to ultraviolet, bordering on the very extreme of human vision, and can cause bright blue fluorescence, and thus a blue rather than violet spot, on many white surfaces, including white clothing, white paper, and projection screens, due to the widespread use of optical brighteners in the manufacture of products intended to appear brilliantly white. On ordinary non-fluorescent materials, and also on fog or dust, the color appears as a shade of deep violet that cannot be reproduced on monitors and print. A GaN laser emits 405 nm directly without a frequency doubler, eliminating the possibility of accidental dangerous infrared emission[citation needed]. These laser diodes are mass-produced for the reading and writing of data in Blu-ray drives (although the light emitted by the diodes is not blue, but distinctly violet). As of September 2011, 405 nm blue-violet laser diode modules with an optical power of 250 mW, based on GaN violet laser diodes made for Blu-ray disc readers, had reached the market from Chinese sources for prices of about US$60 including delivery.[9]
At the same time, a few higher-powered (120 mW) 404–405 nm “violet” laser pointers have become available which are not based on GaN, but use DPSS frequency-doubler technology from 1 watt 808 nm GaAlAs infrared diode lasers. As with infrared-driven green laser pointers above, such devices are able to pop balloons and light matches, but this is as a result of an unfiltered high-power infrared component in the beam.[10] See the section on hazards below, for the difficulties with frequency-doubled IR-pumped lasers.
