iPhasematch vs Desert Storm Atlas

iPhasematch allows you to calculate the phasematching condition of nonlinear wavelength conversion such as SHG or SFM based on published Sellmeier equiations. Downconversion (OPO) can be figured out by the reverse of SFM. It is a subset of the 'Qmix' function of a famous Windows software SNLO by Dr. Arlee Smith. This App does some of what SNLO does on your iOS device. It takes the crystal, two input wavelengths, and temperature and gives the phasematching orientations, effective nonlinear optical coefficients, walk-off angles, angular tolerance and temperature tolerance. In case of SHG, it also gives spectral tolerance. In biaxial crystals, it gives only the phasematching orientations in the principal planes, i.e., either theta=90 deg. or phi=0 or 90deg. Currently supported crystals: BBO, BiBO, CBO, CLBO, LB4, LBO, KBBF, KDP, KD*P, KN, KTP, Mg:LN, Mg:sLN, RBBF, RTP, YAB. NOTE: dn/dT data for LB4 was picked up from discrete data points in the reference and linearly extrapolated. Interface should be intuitive, giving phasematching with a tap of "PM" button,refractive index with "index" button and group index with "Gp.Idx" button, for the given condition (crystal, wavelengths, and temperature). DISCLAIMER: I cannot be held responsible for the result of the calculation it gives. I make every effort to make it accurate, and bug-free, but there could be errors in code. Please just use this on your own discretion.

**January 17, 1991.** As darkness covers Baghdad, cruise missiles streak across the night sky while stealth aircraft slip through Iraqi air defenses. Television viewers around the world watch the opening hours of Operation Desert Storm unfold live. A new era of warfare has begun. The Desert Storm Atlas lets you experience the Gulf War—moment by moment. Through interactive maps, original artwork, and richly connected historical narratives, follow the coalition's campaign from Iraq's invasion of Kuwait through the massive air offensive, the liberation of Kuwait, and the dramatic conclusion of one of history's most decisive modern military campaigns. More than a collection of articles, The Desert Storm Atlas reveals how every event, person, and location fits into the larger story. Discover the political decisions that led to war, the international coalition assembled under the United Nations, the revolutionary weapons and technology that changed modern combat, and the soldiers, airmen, sailors, and leaders whose actions shaped history. ## Inside the Atlas • **64 historical moments** following the Gulf War from Iraq's invasion of Kuwait through the ceasefire • **49 historical figures**, including military commanders, political leaders, coalition personnel, and Iraqi leaders • **40 historic landmarks**, including battlefields, air bases, command centers, memorials, and key campaign locations • **12 in-depth stories** exploring the origins of the conflict, coalition strategy, modern military technology, and the war's legacy • **169 original illustrations** ## Experience the Campaign History unfolded at remarkable speed. Follow the Iraqi invasion of Kuwait, Operation Desert Shield, the coalition air campaign, Scud missile attacks, special operations, the Battle of Khafji, the famous "Left Hook," the liberation of Kuwait City, and the ceasefire that ended one of the shortest major wars of the twentieth century. Discover how stealth aircraft, precision-guided weapons, GPS navigation, Patriot missile batteries, and satellite technology transformed warfare and influenced nearly every major conflict that followed. Powerful cross-references connect every historical figure, landmark, story, and event, helping you understand not only what happened, but why it happened. ## Interactive Maps Every historical moment, landmark, and key figure appears where history happened. Explore Kuwait, Iraq, Saudi Arabia, and the Persian Gulf through interactive maps and satellite imagery. Follow armored advances across the desert, coalition air operations, naval deployments, and the movements that reshaped the battlefield in just one hundred hours of ground combat. ## Listen as History Unfolds The Desert Storm Atlas isn't just designed to be read—it's designed to be experienced. Listen as each moment, story, and landmark comes alive through immersive narration. Whether you're learning about the Gulf War for the first time or revisiting one of history's most significant modern conflicts, you'll experience the campaign in a compelling chronological journey. More than three decades later, Operation Desert Storm remains a defining example of modern coalition warfare and the conflict that introduced the world to a new generation of military technology. --- **History Atlas Collection** *History... as if you were watching it happen—moment by moment.* Discover history's defining events through richly illustrated interactive atlases featuring original artwork, immersive narration, interactive maps, and beautifully connected stories.
