Dangerous tattoo remover from eBay is a MILLION watt laser
推荐理由
builds insanely strong lasers with basically salvaged junk electronics.
说明
这是2019年由styropyro发布的一部演示,主题归在Electronics & circuit design。它讲的是high-power lasers这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:Styropyro tests an eBay laser tattoo removal device and finds it is a roughly million-watt pulsed laser, powerful enough to ignite air in the beam. He had bought it hoping to salvage an Nd:YAG laser cavity.这些读者给出的理由,核心是:HN mostly cites it as an example of the absurdly powerful lasers sold cheaply online, and a nod to the channel's DIY laser builds.讲法不绑某一条新闻,过几年仍然可以当材料看。从2020年到2022年,有1位不同的读者在1个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合先看结果再决定要不要深挖的人。先看它做成了什么。如果已经会了基本定义,就把注意力放在它怎么把high-power lasers变成能跟着复述的例子。
