WebThe velocity was found around iO mIs much higher than that of a detonation wave calculated using LSD model. Since laser intensity at the plasma front was below the threshold for LSD regime, absorptionlexpansion mechanism other than LSD might predominate under the experimental condition. WebRetinal effects are possible when the laser emission wavelength occurs at visible wavelengths, 400 nm to 780 nm, and near infrared wavelengths, 780 nm to 1400 nm.44Laser light directly entering the eye can be focused to an extremely small spot on the retina, 10 μm to 20 μm in diameter.
