我们开发了 100 J 激光器技术,作为实现 1 kJ 级激光器的基础技术。1 kJ 级的激光输出相当于激光聚变反应堆的一个单元激光驱动器的规模。开发由极端光学元件制成的 1 kJ 级激光器使得多种基础技术得以实现,这些技术在激光加工、激光加速、中子产生等领域开辟了新的市场。
这项工作的一部分是在 2016-2021 年由日本新能源和产业技术开发组织 (NEDO) 委托进行的项目“高辉度和高效的下一代激光处理技术开发”中进行的。
激光器具有各种特性,如波长、脉波宽度、能量和脉冲重复频率。根据应用来优化这些特性不仅可以实现高效加工,还可以大幅提高质量或增加不可预测的新效果。这些技术可应用于激光加工、环境测量、材料分析、半导体制造、医疗、空间和基础科学等所有领域。
这项工作的一部分是在 2015-2018 年由日本政府的科学、技术和创新委员会委托“颠覆性技术创新计划 (IMPACT)”项目经理 Yuji Sano 开展的“用于实现安全、可靠和长寿社会的普适高功率激光器”项目中进行的。
我们开发了用作高功率/能量激光器泵浦光源的高功率激光二极管 (LD) 模块。这些 LD 模块具有独特的属性,例如极高的光能量、可变的时间脉冲持续时间和大面积/均匀空间模式,与用于光通信和材料加工的传统 LD 特性相辅相成。我们正在将这些 LD 模块的应用研究扩展到其他应用。
