The beacon problem of adaptive optics (AO) is settled by the promotion of laser guide star (LGS), but the anisoplanatic error due to LGS will degrade the performance of AO system as well.

First-order theoretical model for laser guide star adaptive optics system

The temporal power spectrum of atmosphere turbulence induced wavefront error for laser guide star (LGS) is analyzed According to the power spectrum of phase distortion and transfer function of adaptive optical system, the temporal response errors for LGS and nature guide star (NGS) are compared An optimization method for selecting CCD sampling time of NGS adaptive optical systems is discusse

In the experiments of Rayleigh laser guide star (LGS) for adaptive optics on altazimuth Coudé telescope, the technology of LGS launched and received in the common aperture using polarizing beam splitting scheme is researched.

The main technical index of push-pull laser guided automated vehicle,the characteristics of construction and the function of each main system are introduced in the paper.

The Characteristic of discharge initiated by laser is related to various factors,such as power density of the laser,polarity of the voltage etc.

Research of the hardware-in-the-loop simulation system for laser seeker;

Performance of high-repetition-rate laser jamming laser seeker;

Through analysis of the anti-interference measures against laser seeker of the laser-guided weapon and the jamming mechanism of high-frequency laser against semi-active laser-guided weapon,two implement means of high-frequency laser against semi-active laser-guided weapon were put forward.
