We demonstrated a pulse-to-pulse frequency-tunable LiNbO3 terahertz-wave parametric oscillator, pumped with a Q-switched Nd:YAG laser. Rapid tuning from 1 to 2 THz, with random frequency accessibility, was achieved by rotating the pump beam angle using an optical beam scanner and a telescope....
A computer-controlled scanner allows the generation of moving 3D objects that are viewable from any direction in a prototype device at a 25 脳 25 脳 25mmscale, and larger displays that are based on the colloidal dispersion of SHG crystals are envisioned. Our methodology may have important ...
This invention uses various solid-state semiconductor lasers along with frequency doublers as needed to achieve the required three- color light beam wavelengths for input to available light combiners and to a state-of-the-art scanner. Th... RJ Knize - US 被引量: 137发表: 1994年 Broadband tu...
Standard AFM images were collected simultaneously with the multifrequency maps (see above), but also separately, using an Agilent 5500 microscope equipped with a high resolution scanner and with a chamber for environmental control (Keysight, Santa Clara). The Agilent 5500 is not equipped with multim...

According to certain embodiments, the quadratic approximation can be more accurate than the linear approximation of the first algorithm for at least some temperature values. Because the frequency error over temperature plots for typical crystals are cubic and antisymmetric about a center point, the ...
For a long time it has been known that diacetylene monomer single crystals undergo, upon thermal annealing or exposure to high-energy radiation, topochemical solid-state polymerization. From this reaction, polymer chains are formed which have a substantial π-electron delocalization, f...
We constructed a dual-wavelength optical parametric oscillator (OPO) with two K.TP crystals pumped by frequency doubled Nd:YAG laser. Each KTP crystal was set on a Galvano scanner and the angle of each crystal was controlled independently. The OPO has a tunable range from 1300 - 1900 nm, ...
Single crystals of NiTe2were grown by the Te flux method. Mixtures of high-purity Ni powder (99.99%) and Te ingots (99.9999%) were vacuum sealed in the quartz tube. The quartz ampoule was heated to 1050 °C for 10 h, dwelled for 10 h, then slowly cooled to 600 °C with...
