A quarter century ago, Nd:YAG lasers were capable of optical efficiencies of only a few percent at best. Pump photons, produced by high-power arc...
Minuscule microlasers have numerous potential applications in information technology and communications as well as in medical diagnostics. Scientists...
Metamaterials could permit the creation of ultrahigh-resolution lenses and could even make cloaking devices a reality. To do so, they must reflect...
All-optical switches — those in which one group of photons alters the flow of other photons — are an essential component of many next-generation...
Lasers in the mid-infrared spectral region — often described as the wavelength range between 3 and 30 μm — are very useful in molecular...
Amorphous glasses can exhibit second-order susceptibilities if the material’s inversion symmetry is broken by treatments such as poling or...
