This is an enclosure for the seemingly popular NEJE DK-8-KZ DIY Laser Engraver. I wanted to make an enclose for greater laser safety with concern for other people being around it, namely children who are inquisitive and might harm their eyes by looking at the laser through the open sides. It is easily printable is 2 parts, a base and a top&sides. The design leaves holes for USB connections, fan exhaust and on/off button. The geometry is designed to be easily printable with NO supports on a...

A PMMA Air Force visor with 1.06 micron absorber IR282 and .53 micron absorber K283 was studied for its utility as a laser protective material. The visor material was found to have an optical density approx. 6 at 1.06 micron and approx. 4 at .53 micron with a luminous transmittance of 44%. More bleaching was observed at high irradiance levels for IR282 in PMMA than in MMA. Pulse narrowing effects were noted and taken into account for the optical density calculations. An explanation is given for...

Laser applications have proliferated in recent years and, as to be expected, their presence is no longer confined to the laboratory or places where access to their radiation can be easily controlled. One obvious application where this is so is in military operations where various devices such as laser range finders, target designators, and secure communications equipment elevate the risk of exposure, specifically eye exposure, to unacceptable levels. Although the need for eye protection in the...

As far as the long term exposure to laser radiation of a certain strength by laser workers is concerned, it is possible for it to give rise to reductions in visual acuity, clouding of lenses, as well headaches, anemia, nerve weakness, and other similar bad effects throughout the entire body. The potentially problem causing laser radiations are capable of leading to severe acute disorders. Because of this, personnel in contact with lasers (exclusive of those receiving laser diagnosis and...

With high-energy lasers, not only the direct laser beam can pose significant eye and skin hazards, but also light reflecting off material illuminated by the beam. Proper hazard analysis for a material irradiated by a laser relies upon the reflecting properties of the material surface, as these properties determine the magnitude and direction of the reflected laser energy commonly characterized by the bidirectional reflectance distribution function BRDF. However, a high-energy laser heating and...

Skin damage thresholds were measured and compared with theoretical predictions using a skin thermal model for near-IR laser pulses at 1318 nm and 1540 nm. For the 1318-nm data, a Q-switched, 50-ns pulse with a spot size of 5 mm was applied to porcine skin and the damage thresholds were determined at 1 hour and 24 hours post-exposure using Probit analysis. The same analysis was conducted for a Q-switched, 30-ns pulse at 1540 nm with a spot size of 5 mm. The Yucatan mini-pig was used as the skin...

The result is a method that can be efficiently integrated into existing laser modeling and hazard analysis software....

These molecules useful non-linear optical and optoelectronic properties. The contractor used a synthesis method based on the retro Diels-Alder reaction of porphyrins fused with bicyclo[2.2.2]octadiene units. This yields a new series of conjugated porphyrins that are difficult to be prepared by any other methods.

Exposure of the retinal in an awake, task-oriented animal to brief flashes from a Krypton laser produced immediate changes in visual acuity. The magnitude of the initial deficit was dependent upon the size of the exposure on the fovea. The duration of the deficit, on the other hand, was dependent upon the power density of the exposure. The background wavelength of the target had an effect on the derived recovery functions. Exposures to irradiation levels that produced a permanent shift in...

Exposure of the retina to intense spots of coherent light produces immediate changes in the ability of the animal to perform a visual discrimination task. Relatively large shifts in visual acuity occur during laser irradiation and recovery is somewhat rapid following termination of relatively low-energy, long duration exposures. With more intense energies, recovery is slower and permanent shifts in postexposure spectral sensitivity often accompany these types of exposure conditions. Keywords:...
