Talk:Fiber laser

Old comment

What is really needed here is a whole new article. This article says nothing about fiber lasers in general, but rather seems to have been a brief piece about a specific type of fiber laser, which got mangled together with a slightly rewritten version of itself. --Srleffler 04:56, 14 August 2006 (UTC)

Section removed from article

I've removed the following from the article, because it's not very well written, and I can't tell what it's talking about. Fiber lasers are typically coiled onto a disk, which is convenient not only to fit them into a smaller package but also aids in cooling and can in some cases improve the transverse mode of the output. None of this is novel as of December 2006. Obviously, the ad was about something more specific, but it's not clear from the paragraph below what that is. --Srleffler 06:08, 24 January 2007 (UTC)

According to an advertisement by Hamamatsu in the December 2006 issue of Scientific American, in order to strengthen the reduced level of output power available from a small optical fiber these lasers are now coiled into a disk. This was possible due to collaboration between Hamamatsu and the University of Electro-Communications in Tokyo.

An inaccuracy

I am thinking of changing the second sentence which isn't strictly true. It currently reads: "They are related to doped fiber amplifiers, which provide light amplification without lasing." Fibre amlifiers do work by a lasing process. Ie. they literally work by Light Amplification by Stimulated Emission of Radiation. Vectis Kitsune (talk) 10:27, 8 November 2010 (UTC)

The modern definition of a laser is narrower than the acronym implies. By definition a laser has amplification by stimulated emission of radiation and resonant feedback. An optical amplifier is not a laser. A laser is an optical amplifier inside a resonator. --Srleffler (talk) 01:11, 9 November 2010 (UTC)

Maybe the paragraph works better this way.

"A fiber laser or fibre laser is a laser such that the manufacturer implants rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium and thulium as an alien mass through the active gain medium - a mechanically stretched fiber - so that the pump or pumps can force the ions to undergo population inversion and unleash the laser's power. Fiber lasers are devices with superior heat dissipation, which from a certain point of view makes them among the cool devices. They are related to doped fiber amplifiers, which provide light amplification without lasing. Fiber nonlinearities, such as stimulated Raman scattering or four-wave mixing can also provide gain and thus serve as gain media for a fiber laser." — Preceding unsigned comment added by 103.14.61.146 (talk) 07:58, 13 November 2015 (UTC)

No, and see WP:EGG.--Srleffler (talk) 18:32, 13 November 2015 (UTC)

No, actually I was and am being economical with the reverence, which is sort of like being economical with the truth, except instead of organizationally similar to lying, I was and am organizationally similar to joking. But my conduct is legitimate, thus providing a defense against any and all prohibitions on humor. I had to use links for the audience to ever get the economy with the reverence. 103.14.61.146 — Preceding unsigned comment added by 203.215.119.214 (talk) 14:29, 11 December 2015 (UTC)

Eeeuw :(

This article is garbage. It's all buzzwords and inaccuracies and terrible English; to put it bluntly, b.s. Best solution for this article would be a long walk off a short pier. 116.231.78.79 (talk) 08:32, 23 May 2018 (UTC)

I second this sentiment - truly pathetic. This article reads like somebody is simply promoting their own work, while there is nothing of the actual history of this field. Wikibearwithme (talk) 22:37, 2 July 2018 (UTC)

Thirded. I attempted some cleanup and removed the advertising links, but mostly just inserted cleanup tags. I was much more aggressive than usual with this and deleting things and still feel that I went easy on this abomination. There was no way I could make it worse unless I threw in more Markov-chain ad copy bullshit and weirdly phrased nonsense. If this article had just been the word "penis" repeated 1000 times (which I considered as my edit for a moment), I'd have come out of the experience knowing more about fiber lasers than I do after trying to wade through the obfuscated mess of words that don't exist in dictionaries but aren't technical either and self-promotion of articles published in questionable places that was/is here. Someone who cares and knows about fiber lasers may be able to ditch it and rewrite, which I would recommend, or try to fix it. As things stand my minor curiosity about whether it would be feasible to construct a fiber laser at home has been replaced by an intense hatred of light itself, and I am making it my goal in life to destroy the sun. A Shortfall Of Gravitas (talk) 05:41, 12 January 2020 (UTC)

And now for something completely different

So I ran the old version of the advantages section through a Markov Chain generator (I mainly trimmed it, so the longer version was better) and realized that the markov chain version really could be dumped directly in without changing the writing quality significantly in this case.

• An advantage of fiber lasers over other types include light is already coupled into a flexible fiber. The fact that the light is already in a fiber allows it to be easily delivered to a movable focusing element, which is important for laser cutting, welding, and folding of metals and polymers. Another advantage is high output power. Fiber lasers can have active regions several kilometers long, and so can provide very high optical gain. They can support kilowatt levels of continuous output power because of the fiber's high surface area to volume ratio, which allows efficient cooling. The fiber's waveguiding properties reduce or eliminate thermal distortion of the optical path, typically producing a diffraction-limited, high-quality optical beam. Fiber lasers are compact compared to rod or gas lasers of comparable power, because the fiber can be bent and coiled to save space. They have lower cost of ownership. Fiber lasers are reliable and exhibit high temperature and vibrational stability, extended lifetime, and maintenance-free turnkey operation. High peak power and nanosecond pulses enable effective marking and engraving. The additional power and better beam quality provide cleaner cut edges and faster cutting speeds.

Fibre spelling not just British English

I changed the article because the spelling fibre is the official spelling in all English speaking countries except USA. Commonwealth English as indicated on the optical fibre Wiki article, is generally used in Wiki articles in such cases, although the nomenclature is contentious as countries such as Ireland are not in the Commonwealth but also follow the same spelling.

This is not the talk article to fight the battle of exact geographical areas of use of different spellings and the use of the word Commonwealth, with respect to the name of the geographical area where the spelling is spelling fibre or fiber, but it should follow other Wiki pages where fibre/fiber spelling is shown.
