Description
A self-consistent model copper vapor laser (CVL) is very helpful for characterization of the copper laser and its implementation. It uses vapors of copper as the lasing medium in a 3-level laser. It can produce green laser light (510.6 nm) and yellow laser light (578.2 nm). The peak power of the laser pulse can be between 50kw and 5000 kw. The pulse width is typically from 5 nsec to 60 nsec and the pulse repetition frequencies are typically between 2 kHz to 100 kHz. The average power of copper vapor laser is in the range of 25 w to 2 kw. To create vapor, it is necessary to get extremely high temperature, about 1500 0C. Typically, two engineering pulses are required, the first to dissociate vapor molecules, and the second to cause the dissociated ions to lase. The ideal laser discharge circuit consists of a capacitor initially charged to a voltage V0 and a Thyratron with a switching time (Tau-s) and discharge tube. A thyratron is a type of gas-filled tube which used as a high-power electrical switch and controlled rectifier. The Thyratrons handle currents are much greater than hard-vacuum tube’s currents. The discharge circuit for the real laser simulates the actual circuit which use in VENUS laser. The real CVL model differential equations circuitry represent the system behavior. Tau-1 and Tau-2 are time delay parameters of model current I1 and I2 (circuit lumped inductances (L1, L2) delays in time which causes by electromagnetic interferences). We characterize the CVL model discharge circuit by a set of differential equations and related parameters. We study of possible changes in the structure of the orbits of delay differential equations (DDEs) depending on variable parameters.
