neodymium glass laser
2.Laser shock processing is a new technique for surface strengthening of small holes In this procedure, the choice of laser parameters is the critical factor The paper investigates a method for optimizing the laser parameters used Based upon the method, a series of laser shocking experiments were performed on a Q switched neodymium glass laser Fatigue test results show that the fatigue life of small holes has been greatly increased after processing:the average fatigue life of laser shocked holes being 2 2 times that of unprocessed ones
3.The results reveal that the composition with 60% in mole P2O5 has the highest refractive indices(1.522 0),lowest glass transition temperature(352.4 ℃),good relative chemical durability 0.52 mg/(cm2.d)and suitable thermal expansion coefficients(128.427×10-7/℃). This material is better candidate as the edge-cladding glass for neodymium phosphate laser glass.
