CIRCUIT ARRANGEMENT OF GAS LASER ELECTRONICS WITH ABSORPTION CELL

摘要

The subject of this solution is a circuit arrangement for the automatic operation of a gas laser with an absorption cell so that diagnostics can be carried out without other instruments and with the possibility of connecting to computer equipment. The principle of the solution is that the first output (61) of the generator (6) is connected through the first frequency divider (5) through the first reader (3) equipped with the first indication (3) and through the first digital-analogue converter (2) with the first input (51) of the summing amplifier (1) and the second output (62) of the generator (6) is connected through the second frequency divider (7) through the second counter (8) equipped with the second indication (9) and the second digital-analogue converter (10) with the second input (52) of the summing amplifier (1). Its third and fourth outputs (53,54) are connected through the switching circuit (11) with the output of the circuit (12) of the electronics of the third harmonic element of the signal, one output of which is connected to the output circuit (13) to indicate the absorbing components and with an indicator (14) of the signal level of the third harmonic element; the third output (63) of the generator (6) is connected to the circuit (12) of the third harmonic component which is connected to the input amplifier (19).<IMAGE>
