“…At last the input pulse is generated by a close loop feedback control process, which uses an electro optic modulator driven by an electrical pulse from arbitrary waveform generation (AWG) to vary the intensity of light at the input of the system [13][14][15]. In general, the complete calcul ation needs complicated codes (For example, the SG99 in SG-III laser facility [16,17], the RAINBOW in OMEGA [9,18], the Miro in LMJ [19] and the LPOM in NIF [20,21]) which contain the spatial and temporal distribution, and so a lot of parameters are required which are difficult to obtain. It's inconvenient to some flexible laser facility such as TIL.…”

The laser driven inertial confined fusion experiments require careful temporal shape control of the laser pulse. Two approaches are introduced to improve the accuracy and efficiency of the close loop feedback system for long term operation in TIL; the first one is a statistical model to analyze the variation of the parameters obtained from previous shots, the other is a matrix algorithm proposed to relate the electrical signal and the impulse amplitudes. With the model and algorithm applied in the pulse shaping in TIL, a variety of shaped pulses were produced with a 10% precision in half an hour for almost three years under different circumstance.

The semi-automatic system for laser beam alignment was developed and researched. The alignment system was used to make the laser beam follow the predetermined path through the optical scheme (basically a series of reflective surfaces such as mirrors or lenses). The algorithm and the software to control the system was developed and tested. The system contained of diode laser source, two gimbal mirror mounts with stepper motors, multi-axis motion controller, near field sensor, far field sensor, wavefront sensor, and control software. It allowed to control the positioning of the beam, tip-tilt and overall curvature of the wavefront.

The shroud removal system is an important part of the cryogenic target project. Based on research status of the cryogenic target shroud removal system, this paper presents a solution of AC servo control system using programmable multi-axis controller. The superior performance of the controller and the latest technology of AC servo control system provide a strong support for the solution. We complete the hardware system design and the development of PC software control system. On this basis, we carry out the shroud removal experiment. The experimental results show that the solution can basically reach the technical specifications of the cryogenic target shroud removal system.
