Dynamik der Schichtabscheidung von Keramiken mit KrF-Excimer-Laserstrahlung
The dynamic during pulsed laser deposition of Al2O3, BaTiO3 and ZrO2 is investigated. The expansion of the laser induced plasma is analytically described as a function of the processing variables and material parameters, considering elastic or inelastic collisions between the ablated particles and …

Pulsed Laser Deposition von Er:ZBLAN-Schichten für den Aufbau eines integrierten Wellenleiterlasers im grünen Spektralbereich
A production of laser active Er:ZBLAN thin films (1um) with pulsed laser deposition (PLD) on MgF2 substrates is presented in this dissertation. Er:ZBLAN films with low droplet density (<10 per 100x100um2) were produced with PLD for the first time. Optical properties (absorption- and emmision …

Herstellung von dünnen Elektrolytschichten mittels Laserablation und Kathodenzerstäubung für Hochtemperatur-Brennstoffzellen
Solid oxide fuel cells (SOFCs) are presently operated at temperatures between 800 and 1000°C. Lowering the operation temperature to 600°C at unchanged power density would increase the durability of the fuel cell stack. Alternative electrolyte materials with a higher electric conductivity and …

Abscheidung von Neodym-Phosphatglas mittels pulsed laser deposition zur Fertigung integrierter Wellenleiterlaser
An integrated waveguide laser can consist of a pump diode laser monolithically joined to a thin film deposited in front of a pump diode on a common mount. For this purpose, a material suitable for low-temperature processing and integration with optical and electronic components has to be …

Diamond-like carbon and ceramic materials as protective coatings grown by pulsed laser deposition
A rather large number of nitride, carbide, and oxide thin films are used as hard and wear-resistant coatings, for optical, corrosive, and refractory applications that are of crucial importance. Additional requirements place even more stringent conditions on the deposition processes. The properties …
