Transmission of Light by Crystals with Deep Impurities Affected by a Contribution of Two-Center Mechanism of Nonlinear Photoexcitation

详细

It is demonstrated that transmission of laser light sharply decreases on a time scale of several nanoseconds with increase in light intensity in the range of ~10⁵–10⁶ W/cm² when a two-center mechanism of nonlinear photoexcitation of a transparent crystal with high concentration of deep impurity centers is taken into consideration.
