Modern laser systems have paved the way for spaceborne laser applications such as Earth's surface and atmosphere monitoring. Well known technologies like Nd:YAG lasers are often employed; however, they do not always comply with all the different requ

Spaceborne LIDAR systems with high power laser optics enable advanced understanding of the climate change. However, nano-scaled particles originating from film deposition processes reduce the laser-induced damage threshold. A secondary ion source is

Atomic layer deposition (ALD) has been widely used in Micro-electronics due to its self-terminating process. The ALD films have precise thickness and nodular-free structure, which are desirable properties for high power laser applications. ALD Al2O3

As a consequence of the statistical nature of laser-induced damage threshold measurements in the nanosecond regime, the evaluation method plays a vital role. Within the test procedure outlined in the corresponding ISO standard, several steps of data

Laser-Induced Damage in Optical Materials: 2015.
The role of thin-film interfaces in the near-ultraviolet absorption and pulsed-laser–induced damage was studied for ion-beam–sputtered coatings comprised of HfO2 and SiO2 thin-film pairs. To separate contributions from the bulk of the film and fr

As a consequence of its statistical nature, the measurement of the laser-induced damage threshold holds always risks to over- or underestimate the real threshold value. As one of the established measurement procedures, the results of S-on-1 (and 1-on

In the determination of the laser-induced damage threshold (LIDT) of optical coatings former Round-Robin experiments stand as the empirical foundation for the development of the International Standard as it is known today. In 1983 and 1997 such exper

Atomic Layer Deposition (ALD) allows for the deposition of homogeneous and conformal coatings with superior microstructural properties and well controllable thickness. As a consequence, ALD-processes have moved into the focus of optical thin film res
