Characteristics of laser-induced damage in K9 glass based on ANSYS
Abstract:
Characteristics of damage in K9 glass irradiated by pulsed lasers were analyzed, based on the three-dimensional model of transient heat conduction and the finite element method software ANSYS. Simulation results show that the thermal stress damage in K9 glass is determined mainly by the hoop stress, and the bulk damage occurs earlier than surface damage below the melting temperature. The tensile stress damage caused by the Gaussian beam is slightly higher than that caused by the flattop beam at the same irradiation energy. Also, the inclusion has strong absorption to the laser energy due to electric field modulation, and the stress on the rear surface is higher than that on the front surface.

Characteristics of JFET
The core of a JFET's operation is controlling drain current by modulating the gate-source voltage. When the drain and gate voltage are set to zero, the JFET exhibits no net current flow, representing a state of equilibrium. The drain current increases linearly as the...
