Application of LNA lasers to helium optical pumping
Electron spin-polarized helium 2$\sp3$S$\sb1$ metastable atoms are a valuable probe of spin-dependent phenomena. Helium metastable atoms can be polarized by illumination with circularly-polarized 1.083 $\mu$m 2$\sp3$S$\sb1 ...
Development of a high power, ultrashort pulse laser system
This work focuses on the development of a new high power, ultrashort pulse dye laser system based on solid state Nd:YAG pump sources for a synchronously pumped dye laser and a series of dye amplifiers. This system will be ...
Pulsed ultraviolet laser ablation: Theoretical considerations and applications in medicine
Pulsed ultraviolet lasers can be used to induce clean etching in organic and some inorganic materials. This effect is called photoablation or ablative photodecomposition. Although the precise cause remains unknown, this ...
Polarization reversal in thin film lithium niobate on silicon
The spontaneous polarization of thin film LiNbO$\sb3$ has been shown to be reversible with the application of an electric field at room temperature. This electric field is applied across the sample in the form of a voltage ...
Deposition, characterization, and applications of thin film lithium niobate
Ferroelectric thin films of lithium niobate have been epitaxially grown on a variety of silicon and gallium arsenide substrates by reactive r.f. sputtering. The deposition process was optimized by independently varying the ...
