Considering from the current situation to the future, the application of practical laser material can be mainly divided into the blue, green and violet and visible light laser material for full-color displays, optical storage, lithography and other applications, or 2 ~ 5μm mid-infrared laser material for eye-safe, remote sensing, optical communications, medical and other applications, or 1μm-band high-power, high-energy laser material for advanced manufacturing technology, "new concept" laser weapons, or Diode-pumped laser (Diode pump Laser, DPL) and amplified ultrafast laser gain media materials.
Among the above high power, high efficiency, high-energy solid-state laser crystal materials and DPL speed laser crystal materials should be classified as the key problem with the common direction of basic science [1-4].

A Study on the Prediction and Comparison of processing using the Artificial Neural Network in Nitinol Electrochemical Machining WooJae Song1,a, EunSang Lee2,b 1Graduate School of Metal Materials and Machining Process Engineering, Inha University, Incheon 22212, Republic of Korea 2Department of Mechanical Engineering, Inha University, Incheon 22212, Republic of Korea atorsten@inha.edu, bleees@inha.ac.kr Keywords: Nitinol(SMA), Electrochemical Machining, Artificial Neural Network, Machining Prediction Abstract.
In addition, there is a limit to the application of the Design of Experiments(DOE- RSM,Taguchi), which requires the highest precision of machining, to the machining processing of the advanced composite materials that are difficult to machining. [6] Therefore, this study applied Artificial Neural networks to electrochemical machining(ECM), which provide more accurate data than traditional Design of Experiments(DOE).
Therefore applying DNN to advanced materials, such as machineability shape memory alloys(SMA), provides more accurate predictions and results compared to traditional design of experimental(DOE) methods.

Dismantling is the first step for WEEE processing, which will mainly separate components containing hazardous substances or valuable materials.
The resource productivity equals gross industrial production of the enterprise divided by recycled material resource consumption in this year Materials improvement rate is to assess the results of performance improvement for the recycled material compared with the original waste material.

Introduaction In the application of composite materials, the plane woven fabrics are being widely used as reinforcement.
However due to the bad flexibility of glass fibers or carbon fibers, it often needs to cut across fabrics to satisfy the deformation of shaped fabrics when weaving shaped composite materials.
