SRI measures the roof's ability to reject solar heat, defined such that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100. [44] A perfect SRI is approximately 122, the value for a perfect mirror, which absorbs no sunlight and has very low emissivity.
Dielectric mirrors are also used to produce ultra-high reflectivity mirrors: values of 99.999% or better over a narrow range of wavelengths can be produced using special techniques. Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti-sapphire laser .
It uses 173,500 heliostats, each with two mirrors focusing solar energy on boilers located on three 459 feet (140 m) tall [9] solar power towers. [8] The first unit of the system was connected to the electrical grid in September 2013 for an initial synchronisation test. [10] The facility formally opened on February 13, 2014. [2]

Q-switching, sometimes known as giant pulse formation or Q-spoiling, [1] is a technique by which a laser can be made to produce a pulsed output beam. The technique allows the production of light pulses with extremely high peak power, much higher than would be produced by the same laser if it were operating in a continuous wave (constant output) mode.
