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 ...
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 ...
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 ...
