Nd:YAG Laser Mirrors feature high damage thresholds.
2015-06-22 14:31:06| Industrial Newsroom - All News for Today
With all-dielectric Ion Beam Sputtered coatings, TECHSPEC® High Power Nd:YAG Laser Mirrors provide reflectance up to 99.9% at 45° incidence. UV-grade fused silica mirror substrates are polished on both sides, which allows user to monitor transmitted light leakage through backside in demanding laser applications. Available in 0.5, 1.0, and 2.0 in. diameters, mirror models include YAG fundamental at 1064 nm, second harmonic at 532 nm, and UV versions at 355 and 266 nm.

Plate Beamsplitters offer high laser damage thresholds.
2015-05-04 14:31:05| Industrial Newsroom - All News for Today
Insensitive to input beam's polarization state, Laser Line Non-Polarizing Plate Beamsplitters feature high laser damage thresholds of greater than 6 J/cm² at 1064 nm at 10 ns. Coating with dielectric layers offers λ/8 surface accuracy for minimal wavefront distortion. Manufactured using fused silica substrate, beamsplitters have clear aperture of greater than 22.9. Units come in four 25.4 mm diameter models with design wavelengths of 355, 515–532, 770–830, and 1025–1095 nm.
Broadband IR Laser Mirrors exhibit high damage thresholds.
2015-01-15 14:31:08| Industrial Newsroom - All News for Today
Available in 25 and 50 mm dia sizes, RoHS-compliant Broadband IR Laser Mirrors feature copper substrate. Resulting laser damage threshold is 50 kW/cm² (typ), and substrate also dissipates excess laser-generated heat to promote mechanical stability. Suited for demanding IR laser applications, such as those using quantum cascade or CO2 lasers, mirrors feature greater than 98% reflectivity from 2–20 µm with surface accuracy of 1/20λ at 10.6 µm and Clear Aperture (CA) of 90%.

Parts of Pacific Ocean close to El Nino thresholds: Australia weather bureau
2014-12-16 05:48:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Surface temperatures of the equatorial Pacific Ocean have exceeded El Nino thresholds for several weeks and there is a greater than 70 percent chance of the weather pattern emerging, the Australian Bureau of Meteorology (BOM) said on Tuesday. The BOM had earlier projected at least a 70 percent chance of El Nino arriving by February 2015. The weather event occurs every four to 12 years and can trigger drought in some parts of the world while causing flooding in others. "Typically, after the ocean...
