The field of laser parameter measurement, some test techniques and results have been published in international academic conferences and foreign important academic journals. In 2016, the measurement results of the noise ratio of the measuring system were made, which enabled the laboratory to achieve world-class work in this field.
Optical path automatic collimation system is an indispensable part of all large high power laser pointer devices. The automatic alignment of the optical path of the laser beam is an important part of the operation of any laser device that must be operated before the shooting experiment. Laser device for optical path automatic alignment of the system design requirements include adjustment accuracy and adjustment time of the index requirements. The accuracy of the adjustment includes the angle of the far field of the beam, the accuracy of the angle adjustment, the center shift adjustment precision of the beam near the beam, the translational precision, the rotation accuracy of the beam near-field rotation adjustment accuracy.
At the time of the device, the optical system of the optical system debugging mainly rely on manual debugging, researchers should laser oscillator output of the seed light source, along a 100 m optical path, accurately through the center of each optical element, and ultimately reach the target Room and accurately focused on the target. The amount of work required here, the time required and the collimation accuracy determined by the human eye can not meet the experimental requirements of the larger device.
In the development of the device, burning laser pointer optical path automatic collimation system research and development has received a high degree of attention. According to the requirements of the device, innovation "optical path automatic collimation system in the dynamic correction, black and white alignment correction, small step to adjust the technology." So that the automatic calibration time of the eight-beam laser system is only 15 minutes, and the accuracy of the automatic positioning by the computer is much better than the accuracy of human positioning. Which has made an important contribution to the efficient and stable operation of the device for 15 years.
Integrated device centralized control system design goal is to achieve a high degree of automation device management, management of electronic, all-round to improve the efficiency and level of operation of the device to better serve customers in the physical experiment needs. The centralized control system needs to integrate the subsystems of the integrated devices to complete the data acquisition, analysis, management, control and monitoring functions necessary for the operation and maintenance of the equipment. The new and old devices can be mixed under the same network system.
The main research and development content of the centralized control system is: the development of energy terminal control system; the new 20mw laser pointer parameter acquisition and storage; remote control management of the synchronization unit, the remote modification of the synchronization parameters and the synchronization parameter storage for each experiment; the management information system The expansion of the database system design; in the improvement of the sub-system terminal control software on the basis of the development of central control software system.
The application of this solution can greatly simplify the structure of the system, reduce the number of interface components, to overcome the host computer and industrial controller, between continuous control and logic control, between the concentration and dispersion of the boundaries. At the same time, the fully integrated automation solution can provide a unified technical environment for all automation applications, including: unified data processing, unified communication, unified configuration and programming software and software quality control. Will eventually through several operators in the total control room command control system to achieve the normal operation of the entire device. Laser parameter measurement technology With the generation of high-power laser device development, as a high power laser important unit technology 5mw laser pointer monitoring and control has also been rapid development.
