Development of Compact Laser Systems Using 3D printing Techniques for Stand-Off Laser Spectroscopy Shuo Li, Ran Zou and Kevin P. Chen* Department of Electrical and Computer, University of Pittsburgh, 3700 O’Hara Street, Pittsburgh, PA 15261, USA Xi Huang, Lei Liu, and Yongfeng Lu Department of Electrical and Computer Engineering, University of Nebraska-Lincoln, Lincoln, NE 68588, USA Email: [email protected] Compact, robust, and energy-efficient lasers play critical roles in various laser remoting sensing applications in fields such as laser Raman and laser-induced breakdown spectroscopy (LIBS) techniques. This paper discusses the development of compact and portable Q-Switched Nd: YAG lasers with multi-pulse output and their applications in laser remote sensing. Using a vertical-cavity surface-emitting laser in an end-pump scheme and 3D printing technique, we describe a new approach to produce compact and lightweight laser system with outstanding thermal-mechanic properties. The applications of compact laser systems will be discussed in LIBS.
