| 説明 | A shot of my 450mW 532nm high-power green IR-DPSS-FD laser crossing beams with my 300mW 650nm (+-10nm) high-power red direct-diode semiconductor laser. This image was taken with both lasers sitting on the floor of my room, making obvious the dust on the floor (the scatter really makes the dust pronounced). As you can see from this image, the DPSS laser (the green one) has a much more pure beam than the red laser (which is just a semiconductor diode laser). Rayleigh scattering has made the green laser beam very pronounced, but the red laser beam still is visible (I'll try to mark it out with in-image notes). Also, my camera didn't do justice to the red laser; the red color of the laser is actually a lot deeper (and, in my opinion, prettier) than it is shown to be in the picture.See also this shot, which features my green laser in the same position as it is in in this image, but sans the red laser.DANGER: The lasers shown here are class 3B laser devices. Class 3B lasers are NOT laser pointers, and should never be used for that purpose. Despite the fact that I took the picture with the lasers sitting on the floor of my room, and despite the fact that I seem to have fun when using my lasers (I do), I took proper safety precautions to ensure that myself and others do not get injured; for example, I wore ANSI Z87.1-standard green laser safety goggles at all times when the laser was operating (the red laser didn't present as much of a hazard as the green laser in this setup due to its position).In other words, unless you know what you're doing, DO NOT TRY THIS AT HOME. You could inadvertently blind yourself or someone else. And, of course, high power laser devices should NEVER be pointed at other people, and lasers of any kind should NEVER be pointed at aircraft, especially those in flight. High-power lasers like these should be treated with the same respect as you would treat a loaded gun.Please be aware that high power laser devices may be restricted by laws in your area.You can download the full resolution version of this image from my website by clicking here, then clicking on the Full resolution link. |
