Effects in the population inversion of3H4 level in Tm, Tm-Tb and Tm-Eu doped germanate glasses for amplifiers applications
(2006-10-16)
The population inversion of the Tm3+ in GLKZ glass involved in the 1470 nm emission (3H4 → 3F 4) as a function of Tb (or Eu) concentration was calculated by computational simulation for a CW laser pumping at 792 nm. These ...

In vitro studies of femtosecond pulse interaction with bone
(2008)
Lasers utilization in biomedical areas is a growing area, in spite of the collateral thermal damage that they can cause in the surrounding tissue. The purpose of this study is to analyze, in vitro, the ablative interaction ...
Control of nonlinear absorption and amplification of light in Er3+-doped fluoroindate glass
(1999-11-01)
Nonlinear absorption and amplification of a probe laser beam can be controlled by adjustment of the intensity-modulation frequency and the wavelength of a pump laser beam. A demonstration of this effect in Er3+-doped ...

Pump pulse-width dependence of grazing-incidence pumped transient collisional soft-x-ray lasers
(American Physical Society, 2007-12)
The output energy dependence of high repetition rate grazing incidence pumped Ni-like Mo, Ni-like Ag, and Ne-like Ti transient collisional soft x-ray lasers on the duration of the pump pulse was studied combining experiments ...
Penetração e alterações teciduais do laser de alta intensidade em tecidos moles e duros da cavidade bucal
(Universidade Federal de Minas GeraisUFMG, 2018-07-13)
The treatment of several odontogenic cysts and tumors is commonly associated with an adjuvant therapy, aiming for lower recurrence rates and a better prognosis. There are some related methods however, to our knowledge, the ...
