Characterization of ultrashort pulses by a modified grating-eliminated no-nonsense observation of ultrafast incident laser light E fields (GRENOUILLE) method
Heisler, Ismael Andre; Correia, Ricardo Rego Bordalo; Cunha, Silvio Luiz Souza (2005) [Artigo de periódico]The measurement and characterization of ultrashort laser pulses remains an arduous task. The most commonly used pulse-measurement method is known as frequency-resolved optical gating (FROG), and another version with great ... -
Molecular dynamics investigation with the time resolved optical Kerr effect on the CS2–C6H6 mixtures
Heisler, Ismael Andre; Correia, Ricardo Rego Bordalo; Cunha, Silvio Luiz Souza (2006) [Artigo de periódico]An investigation of the molecular dynamics in pure liquids and in mixtures through the technique of time resolved optical Kerr effect is performed. The samples studied were the mixtures of carbon disulfide (CS2) with benzene ... -
Reflexões sobre o EAD no ensino de física
Cunha, Silvio Luiz Souza (2006) [Artigo de periódico]São apresentadas algumas reflexões sobre o uso das Tecnologias de Informação e Comunicação (TICs) e do Ensino a Distância (EAD) no ensino da Física. Em particular discorremos sobre as motivações, as condições e o potencial ... -
Study of nascent NaH in sodium-hydrogen mixture using resonant CARS and FWM processes
Correia, Ricardo Rego Bordalo; Cunha, Silvio Luiz Souza; Pichler, Goran; Hering, Peter; Motzkus, M. (1992) [Artigo de periódico]The Coherent anti-Stokes Raman Spectroscopy (CARS) technique was applied to measure the O Q, and S branches from the first, second and third overtones of the XICt ground state of NaH. Moreover, P and R doublets were also ... -
Time-resolved optical Kerr-effect investigation on CS2/polystyrene mixtures
Heisler, Ismael Andre; Correia, Ricardo Rego Bordalo; Buckup, Tiago; Cunha, Silvio Luiz Souza; Silveira, Nádya Pesce da (2005) [Artigo de periódico]The relaxation dynamics of carbon disulfide are investigated in mixtures with polystyrene (PS) using the time-resolved optical heterodyne-detected optical Kerr effect (OHD-OKE). The data are analyzed using both the ...
