One New Rapid Prototyping Energy Based on Laser Diodes

针对快速成型技术中存在的问题,提出了一种可选址驱动的半导体激光器线阵能量源新方案.在计算机软件与硬件控制下,以带尾纤的低功率半导体激光器光纤输出端集成的方法设计和实现了选址驱动能量源线阵雏形.用两组半导体激光器光纤输出端线阵交错排列补偿以形成一维长度为10mm、宽度为0.25mm连续线阵能量源.该方案原理可行,为将来实现高功率半导体激光器阵列在快速成型技术中的应用提供了坚实的基础.

Aim at the existing issues in rapid prototyping (RP), a new design of forming a new energy featuring an addressable array of fiber-coupled laser diodes is brought forward. Under the control of computer software and hardware, the project of integrating the fiber with the pigtail power laser diode is designed to realize the addressable energy source. To from a 10 mm continuous liner light energy, multi-array of fiber-coupled laser diodes with discreet output light spots are arranged to compensate the space between the spots. The basic technique study of the array of fiber-coupled laser diodes demonstrates the principle feasibility of this project, providing the solid foundation for the application of array of high power laser diodes in RP in the near future.
