Re: LED Laser, Jan '10, page 22. I may be a litthe late on this, but while scanning through the Jan issue of Nuts & Volts I was alarmed by the first question in your column. The description of the "IR LED laser" bought on eBay was disturbing (as was the intended use, of "cutting some plastics").rnA laser is a laser - not an LED - and can be extremely dangerous. A 30W IR laser (which is probably in the 808 nm range) can easily cause permanent damage to your eyes in an instant and should be operated with great care. Likewise, laser ablation (and burning, which would certainly occur with this laser) of certain plastics (such as polycarbonate) can release harmful vapors.

机译：回复：LED Laser，2010年1月10日，第22页。我可能对此还不太了解，但是在浏览一月的《坚果与伏特》时，我对您专栏中的第一个问题感到震惊。在eBay上购买的“ IR LED激光器”的描述令人不安（正如预期的用途，是“切割某些塑料”）。rn激光器是激光器，而不是LED，并且非常危险。 30W的红外激光（可能在808 nm范围内）很容易立即对眼睛造成永久性伤害，应格外小心操作。同样，某些塑料（例如聚碳酸酯）的激光烧蚀（和燃烧，肯定会在这种激光下发生）会释放出有害蒸气。
