Talk:Blue laser

Is this really neccessary?

Why does blue ray redirect here as opposed to going to the page for bluray?Bushido Brown 17:54, 12 May 2007 (UTC)

I agree, searching for "blue ray" should not redirect here. I will try to change it. But as of right now I don't know how.The Goat 16:32, 2 July 2007 (UTC)

When you put in "blue ray" it will say "redirected from blue ray" with a link to blue ray. Click on that and you can edit the redirect, so it, well, doesn't redirect. 72.74.117.222 00:37, 13 August 2007 (UTC)

I changed the redirection today. Michilans (talk) 12:43, 9 February 2009 (UTC)

Lots more material needed

I came to WP hoping there would be lots of info on blue lasers. I was quite disappointed. Perhaps when I have found something I will add it here because this is an extraordinarily important topic. Royzee (talk) 18:03, 19 December 2007 (UTC)

Do we really need to know about the 3rd in the world polish blue laser?

I doubt that. Yes. We do. —Preceding unsigned comment added by 83.25.251.51 (talk) 20:37, 10 April 2011 (UTC)

405nm DPSSFD?

What would a 405nm DPSSFD laser (as alluded to under "Appearance") use as its 810nm source? Or are 405nm lasers all GaN? —Preceding unsigned comment added by Moletrouser (talk • contribs) 06:48, 21 September 2010 (UTC)

I think they would use an IR 808nm Diode which would make them 404nm, such a small difference that for all intents and purposes, makes no difference. 71.84.126.174 (talk) 04:49, 24 October 2010 (UTC)

Why does this page exist?

Do we also need a page for blue flowers? Blue Birds? Blue cars?... "Blue" is not a technology. It's not even a specific wavelength. It's a color---an aspect of human visual perception. — Preceding unsigned comment added by 129.42.208.179 (talk) 20:11, 24 May 2016 (UTC)

I would suggest that it should exist because the blue laser, particularly the semiconductor variety, is rather different to any other colour of laser, and if all lasers were described in one page it would be rather unwieldy. Solid state lasers with optical powers in the 1 - 10 Watt range are now routinely available and used in applications from tattoo removal to engraving and cutting. Maybe the topic could be rebadged Evolution of solid state lasers? Also need to identify and cover the safety aspects for these devices. Graeme49.193.106.135 (talk) 05:28, 19 December 2020 (UTC)

Magnetic Levitation Devices

I have done some searching and can't find any evidence at all that blue lasers have a use in such systems, so I have removed it. If someone knows better, please put it back in with a supporting reference, and make the appropriate addition to the Magnetic Levitation page.

It is possible that some levitation systems might use lasers as part of the control system, to measure vertical or lateral position for example, but that would not dictate that a blue laser, in particular, would need to be used.

Make pages for other colored lasers maybe?

Why do blue lasers get their own Wikipedia page but other colors of lasers don’t? I find this to be quite strange and unfair o other colors of lasers, and we should make Wikipedia pages for the other colors of lasers. Such as green lasers or red lasers. 75.172.83.3 (talk) 00:40, 18 May 2022 (UTC)
