The laser dazzling effect has always been a crucial issue for the scientific community. Nevertheless, the experiments to study the laser dazzling effect may cost a lot. Therefore, the technology of simulation is promising for this field. Additionally, the effectiveness of the laser dazzling needs to be evaluated by a no reference cost functions. A general model of CCD is proposed in this paper. Additionally, two cost functions are proposed to evaluate the image. The simulation result based on the model shows feasibility of the cost functions. Afterwards an experiment is carried out to testify these cost functions. Different factors include the intensity of the irradiance, the beam radius and the dazzling location of the laser are taken into consideration. The experimental result shows the cost functions have monotonous relationship with the degree of the laser dazzling. This result indicates that the cost functions can be used in the field to measure the degree of the laser dazzling.

The beam pointing is the most crucial issue for beam combining to achieve high energy laser output. In order to meet the turbulence situation, a beam pointing method that cooperates with the stochastic parallel gradient descent (SPGD) algorithm is proposed. The power-in-the-bucket (PIB) is chosen as the merit function, and its radius changes gradually during the correction process. The linear radius and the exponential radius are simulated. The results show that the exponential radius has great promise for beam pointing.

A novel design of a two-axis fast steering mirror (FSM) with piezoelectric actuators is proposed for incoherent laser beam combination. The mechanical performance of the FSM is tested. The results show that the tilting range of the mirror is about 4 mrad, and the 1st-order resonance frequency is about 250 Hz. A self-designed grating encoder is taken as the sensor, which ensures the optimal precision of 10 μrad. The novel mechanical design can meet the requirement of engineering in incoherent laser beam combination.
