The LBO Crystal Cleaning Handbook: A Comprehensive Guide to Maintaining Your Optical Equipment (1)
1. Introduction to LBO Crystal Cleaning 1.1 Overview of LBO Crystals Lithium triborate (LBO) is a non-linear optical crystal that has been widely used in various optical instruments, including frequency doublers and triplers, optical parametric oscillators, and ultrafast lasers. The crystal has excellent transparency across a broad range of wavelengths, high laser-induced damage threshold, and relatively large non-linear coefficient, making it an attractive choice for many applications. However, LBO crystals are susceptible to various types of contamination, which can significantly impact their performance. Contamination can occur in various forms, such as dust, fingerprints, water spots, or even oxidation, resulting in …
