SBIR Phase I: Multipass Second Harmonic Generation

这个小型企业创新研究(SBIR)第一阶段项目计划开发基于多通道二次谐波(SHG)的创新蓝绿激光器。它利用一个简单的伽利略望远镜来解决与这一前景看好的技术方法相关的许多问题。第一阶段可行性研究的目标是开发一种输出功率为20毫瓦、光束质量优良的多程倍频激光器。预计拟议中的激光器的可靠性将是氩离子激光器和倍频激光器的2至5倍(首次故障的平均时间为20,000小时，而不是4,000至10,000小时)。这个项目的商业应用包括生物仪器(光诱导荧光显微镜、流式细胞仪、毛细管电泳法、DNA测序和共焦显微镜)、半导体检查(光掩模检查、晶片对准、共焦显微镜和晶片过程监控)和复印(高速激光打印机、视频CD存储以及医疗成像和诊断)。

This Small Business Innovation Research (SBIR) Phase I project proposes to develop innovative blue and green lasers based on multi-pass second harmonic generation (SHG). It utilizes a simple Galilean telescope to solve many of the problems associated with this promising technical approach. The goal of the Phase I feasibility study is to develop a multi-pass SHG laser with 20 milliwatts of output power and excellent beam quality. The proposed lasers are expected to be 2 to 5 times more reliable than argon ion and frequency-doubled Nd:YAG lasers (20,000 hours mean time to first failure vs. 4,000 to 10,000 hours). In quantity, the parts for the proposed lasers would cost about $625 (vs. several thousand dollars for a frequency-doubled YAG laser).The commercial applications of this project are in bio-instrumentation (light-induced fluorescence microscopy, flow cytometry, capillary electrophoresis, DNA sequencing, and confocal microscopy), semiconductor inspection (photomask inspection, wafer alignment, confocal microscopy, and wafer process monitoring), and reprographics (high-speed laser printers, video CD storage, and medical imaging and diagnostics).
