Problems solved by technology

The filter material currently used in high-power neodymium glass laser systems is mainly a cerium-doped quartz tube, which can only cut off 200-380nm ultraviolet light (CN 103466942 B, yellow ultraviolet filter quartz glass plate and its preparation method; CN104609729 A, dark blue color filter ultraviolet quartz tube and preparation method thereof); and other ultraviolet cut-off filter glass is also limited to 200-400nm wave band (CN 87105349 A, filter ultraviolet filter infrared fluorescent glass); can not satisfy the xenon lamp of the high beam quality neodymium glass laser of repeated frequency Spectrum adjustment needs

Abstract

The invention relates to ultraviolet cut high aluminosilicate crystallized glass doped with cerium and titanium. Filter pipe glass is produced from the compositions in percentage of 40-50mol% of SiO2, 25-35mol% of Al2O3, 5-10mol% of MgO, 0-5mol% of ZnO, 0-5mol% of Li2O, 5-10mol% of TiO2, 0-5mol% of ZrO2, and 3-8mol% of CeO2. The heat conductivity of the produced glass is 1.0-1.2W / MK, and the thermal expansion is between 50*10<-7> / K to 60*10<-7> / K. The produced glass can realize tunable cut for xenon lamp spectra in the range of 200-600nm after being subjected to grinding, polishing and microlite heat treatment. According to the ultraviolet cut high aluminosilicate crystallized glass disclosed by the invention, the heat exchange efficiency of xenon lamps can be reduced to 50% or above, and the heat distortion of neodymium glass under the condition of pumping for the xenon lamps can be reduced by 60% or above, so that the repetition work frequency of neodymium glass lasers is further improved, and the ultraviolet cut high aluminosilicate crystallized glass is hopeful for being used in hectowatt high-frequency neodymium laser systems.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic photoelectric information and functional materials, and relates to a high-aluminum silicon doped with cerium and titanium, which is suitable for a heavy-frequency high-energy neodymium glass laser system and has an adjustable cut-off band in the range of 200-600nm in the xenon lamp spectrum. Salt glass-ceramic and its preparation method. Background technique [0002] Repetition-frequency high-energy neodymium glass lasers have a wide range of application requirements in the fields of laser shock strengthening and titanium sapphire pump sources. However, the poor thermomechanical properties of neodymium glass make it unable to withstand high heat accumulation on the one hand, and cause severe optical thermal distortion on the other hand. Therefore, it is necessary to study a suitable pumping technology to reduce the heat accumulation in the Nd-glass, and then realize the repetition-frequency ...
