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).

该小型企业创新研究（SBIR）第一阶段项目提出开发基于多通二次谐波产生（SHG）的创新蓝色和绿色激光器。它利用一个简单的伽利略望远镜来解决与这种有前途的技术方法有关的许多问题。第一阶段可行性研究的目标是开发具有20毫瓦输出功率和优异光束质量的多程SHG激光器。预计所提出的激光器的可靠性比氩离子和倍频Nd：YAG激光器高2至5倍（首次故障平均时间为20，000小时，而首次故障平均时间为4，000至10，000小时）。在数量上，拟议激光器的零件将花费约625美元（而倍频YAG激光器的价格为几千美元）。该项目的商业应用是生物仪器（光诱导荧光显微镜、流式细胞术、毛细管电泳、DNA测序和共聚焦显微镜）、半导体检测（光掩模检查、晶圆对准、共焦显微镜和晶圆工艺监控），以及 全息照相（高速激光打印机、视频CD存储器以及医学成像和诊断）。
