Thirdly, in order to improve the learning efficiency and stability of feedforward neural network, a fast learning algorithm for neural networks based on CGM-OC approach is presented. Compared with other learning methods such as BP method, Broyden Flecher Goldfarl Shanno method and Powell method in which the derivative is replaced by the difference quotient etc, simulation results show that the proposed method is an efficient and fast one.

The weight values in NLSM were adjusted automatically according to target data, which allowed the measured data with different dimensions or ranges to be treated at the same level, and thus the accuracy and stability of algorithm were improved accordingly. Derivative was replaced by the difference quotient in NLSM which further improved the algorithm speed.

Beijing Institute of Technology, Beijing 100081,ChinaIn order to get the high output power, a RF excited diffusively cooled all-metal slab waveguide CO2 laser was reported, in which gas discharge region was constructed by two aluminum side walls and aluminum electrodes. The region dimension was 2 mm height×20 mm width×386 mm length, and the gas composition was CO2:N2:He:Xe=1:1:3:0.26. This technique replaced the old ceramic and metal sandwich waveguide technique.The optimum out power 127 W was achieved from the RF excited diffusively cooled all-metal slab waveguide CO2 laser with the longitudinal voltage uniformity distribution technique and scaling area technique. The electro-optic conversion efficiency was about 14%.
