A kind of energy attenuation actuator

Technical field

This utility model relates to beam energy attenuating device field, particularly to a kind of energy attenuation actuator。

Background technology

Zlasing mode parameter M²Represent certain particular beam divergence speed in communication process, for a desirable TEM00 laser beam, M²=1。For holmium laser, when directly single pulse energy is adjusted to be in 0.5J-2J time, it is difficult to ensure that a desirable TEM00 laser beam can be obtained every time。In order to obtain close to desirable TEM00 laser beam, current way is directly to regulate laser single-pulse energy, can obtain close to desirable TEM00 laser beam when being controlled within the scope of 1J～2J by Bladder stone single pulse energy。But if it is desired to obtain close to desirable TEM00 laser beam while the single pulse energy of output 0.5J～0.9J, by directly regulating laser single-pulse energy, it is more difficult to obtain。

Utility model content

The technical problems to be solved in the utility model is in that, a kind of energy attenuation actuator is provided, including disc type switch, motor, encoder, described disc type switch includes rotation dish, lens set, the Pan Bi of described rotation dish is horn-like, and the different eyeglass of light transmittance in lens set is arranged on the Pan Bi of horn-like rotation dish。Encoder-driven driven by motor disc type switch rotates, laser traverse is made to make single pulse energy value be reduced to appointment scope after having the eyeglass of certain light transmittance, regulate single pulse energy by this energy attenuator advantageously to focus in hot spot than the mode directly regulating laser single-pulse energy, thus being more easy to the desirable TEM00 laser beam of acquisition。
