　　题目：Laser Damage Modeling at NIF

　　姓名：Zhiming Liao

　　Abstract 

　　The National Ignition Facility (NIF) is the world’s largest and most energetic laser facility. NIF consists of 192 laser beams to produce extreme conditions including temperatures of 100 million degrees and pressures that exceed 100 billion times Earth’s atmosphere. NIF also pushes the envelope of operation for laser induced optic damage by using sophisticate models to ensure the safe and reliable operation of the system. In this talk, laser damage models that deal with laser conditioning of DKDP crystals and damage monitoring and analysis of online fused silica optics will be discussed. 

　　Bio: 

　　Zhi M. Liao is a laser physicist at the National Ignition Facility (NIF), Lawrence Livermore National Laboratory (LLNL). He joined LLNL in 2001 after graduating from University of Rochester where he obtained his B.S., M.S. and PhD in optical engineering, working under Dr. Govind Agrawal on nonlinear fiber optics. His expertise is in nonlinear optics, adaptive optics, and laser-induced optic damage. He has contributed to many of LLNL’s successful laser projects over the years such as the Fiber Laser Guide Star, Alkali Laser, the Mercury Laser, and NIF. He was also the co-PI for the team that won 2006 R&D award for high-average-power frequency conversion using YCOB crystal. Currently, he is the leading researcher at modeling optic damage and lifetime for NIF.  He also directs NIF’s internship and educational outreach program. In 2014, Zhi was named as a senior member of the Optical Society of America (OSA), an international society for optics and photonics scientists, engineers and educators. Senior member status recognizes members with more than 10 years of significant experience and professional accomplishments or service in their fields.
