Study of the fundamental mode TEM00 propagation in stable laser resonators

In this work, a computer program is written in C++ builder to study the TEM00 mode propagation in stable laser resonators. The user can insert optical elements such as mirrors, lens, and laser rods inside the cavity. The program determines the ray transfer matrix (4-4) for each element and draws a schematic diagram for the resonator. It calculates the beam spot of the fundamental mode along the resonator and inside the optical elements and draws two propagation curves along the two axes x and y. (Author)
