Power scaling of Tm:YLF-pumped Ho:YAG lasers
Reported in this thesis are methodologies for power-scaling Ho:YAG lasers for both the continuous-wave (CW) and Q-switched regime. Advancement in Ho:YAG laser power is made possible through the improvements in output power of the Tm:YLF pump lasers. The slab geometry provides good thermal …

Versuche mit gepulsten Nd:YAG- und Ho:YAG-Lasern am in-vitro Truthahn-Modell
… Laserleistung von 15 W bzw. ca. 50 W eines Nd:YAG-Lasers untersucht. Bei 15 W mittlerer Laserleistung kommt es bei Steigerung der Pulsenergie von 1 J/ Puls auf 3 J/ Puls noch zu einer Zunahme der Koagulations- und Karbonisationszone. Bei weiterer Stei-gerung auf 5 J/Puls bei 15 W bzw. einer …

Development of a High Repetition Rate, Electro-optically Q-switched Ho:YAG Laser
… repetition rate, electro-optically Q-switched Ho:YAG laser capable of meeting the requirements for these applications, and as a result, investigate if it is theoretically capable of pumping an optical parametric oscillator. The basis of the research was built upon the development of a …

Novel power scaling architectures for fibre and solid-state sources
… laser architecture was a cryogenically cooled Ho:YAG laser in-band pumped by a diode pumped Tm-doped fibre laser. After determining the absorption bandwidth as a function of temperature at the desired pump wavelength of 1932nm in Ho:YAG, the fibre laser was constructed to have an emission …
