Se presentan los elementos conceptuales que condujeron a la elaboración de un programa de cómputo en Fortran para calcular la potencia de un laser de C02 que se desee construir. En el cálculo se toman en cuenta variables geométricas y ópticas. Debido a que se hacen aproximaciones en las condiciones físicas referentes al funcionamiento de un oscilador laser y para simplificar los cálculos, la aplicación del programa se restringe a potencias en el intervalo de cinco a doscientos cincuenta vatios, operando en onda continua. El cálculo proporciona valores de la potencia que difieren ciertamente de los resultados experimentales, pero dan al usuario una información gruesa sobre el funcionamiento de un equipo laser que se pone en marcha. Tal es el caso al aplicar el programa a un equipo construido en el Departamento de Física de la Universidad Nacional.
The concepts leading to the production of a FORTRAN computer program to predict the output power of a C02 laser to be constructed are presented. In our calculation optical and geométrical parameters are taken into account. The physical assumptions and approxirnations made the program restricted for applications to lasers producing from 5 to 250 watts working in continuous wave mode the computer prediction and the experimental results certainly differ, but they are a rough guide to the proper functioning of a new design, such is the case when the construction conditions of a laser developed at the Physics Departament were entered in the program.
