NIM Staff Paid a Visit to NIST Laser Radiometry Lab

NIM’s technical staff, Ma Chong, Xu Tao and Wang Yanping paid a 5-day visit to NIST laser radiometry Lab from Nov. 12 to Nov. 16, 2011.

During the visit, Ma and his colleagues met NIST optical metrology experts to discuss laser measurement technology and undertook a preliminary comparison with NIST on long-pulse laser source for lasers used in medical applications. The preliminary comparison is conducted at the wavelength of 1064 nm, with a pulse width of 4 ms and energy of ~2 J. The comparison difference is less than 0.3%.
