An investigation of laser-induced damage thresholds (LIDT) of antireflection coated lithium triborates used for second and third harmonic generation were performed at 1064, 532, and 355 nm wavelengths for ~4 ns pulses. Two types of coatings were tested: an anti-reflection coatings with dual peak at 1064 nm and 532 nm and anti-reflection coatings with three peaks at 1064 nm, 532 nm, and 355 nm, respectively. Ion-beam sputtering and magnetron sputtering technologies where used for coatings deposition. Automated LIDT measurements were performed according to the requirements of current ISO 11254-2 standard. The obtained LIDT were in range of 3-15 J/cm2.
