METHOD FOR PROTECTING OPTICAL-ELECTRONIC MEANS FROM IMPACT OF POWERFUL PULSE LASER RADIATION Russian patent published in 2021 - IPC H01L31/232 G02B5/20 

FIELD: optical industry.

SUBSTANCE: invention relates to the field of protection of optoelectronic devices (OED) from powerful optical radiation. The method is based on passing laser pulses through a protective element with a radiation resistance value less than the value of the minimum radiation resistance of the OED elements and protecting the OED by destroying the OED protective element when exposed to a sequence of laser pulses. At the same time, the initial time t_ipe of the effect of a sequence of laser pulses on the protective element and the initial time t_dpe of the destruction of the protective element are determined, the time interval Δt between t_ipe and t_dpe is calculated as Δt= t_ipe-t_dpe, the initial time moment t_iie is determined after the destruction of the protective element the subsequent action of a sequence of laser pulses on an element from the OED composition with a minimum value of radiation resistance and limit the duration of the sequence of laser pulses from the instant t_iie to the instant t_iie+Δt.

EFFECT: invention increases the efficiency of protecting the OED from damage by laser radiation.
