日本新能源、产业技术综合开发机构(NEDO)和制造科学技术中心机构,研制成输出功率3.3kW两种的高功率输出全固体激光器,并获得世界最高水平的成果。最终目的是开发输出功率10 kW以上振荡功率达到20％以上小型的半导体激光器激励Nd:YAG激光器,用Nd:YAG激光可以高速、高质量焊接加工钢铁和铝的厚板。东芝公司,利用棒型的Nd:YAG激光器,其中棒直径8mm,长度120mm,并列4 Japan’s new energy, industrial technology development agencies (NEDO) and manufacturing science and technology center institutions, developed into a power output of 3.3kW two kinds of high-power output all-solid-state lasers, and get the world’s highest level of results. The ultimate goal is to develop a diode laser with an output power of 10 kW or more and an oscillation power of 20% or more. Compact Nd: YAG laser. High speed and high quality welding of steel and aluminum plate with Nd: YAG laser can be achieved.
