Damage Resistance of FiberTech Fibers for High Power Laser Applications

Single pulse Nd:YAG-laser-induced damage thresholds (LIDT) were determined in accordance with ISO 11254 standard for 1064 nm and 532 nm wavelength in the 10-ns pulse duration regime. Using an LIDT measurement setup described in [1,2], Gaussian beam diameters of 50 µm (1064 nm) and 30 µm (532 nm) were achieved.

Single pulse LIDT values for various FiberTech® fibers and a wavelength of 1064 nm are shown in Figure 1. A clear trend towards an enhancement of the damage resistance of the FiberTech® fibers with increasing core diameter is found. FiberTech® fibers reach LIDT values above 500 J/cm2 for a core diameter of 600 µm.
