By using a new saturable absorber V3+:YAG, flash-lamp-pumped passively Q-switched Nd:GdVO4 laser at 1.34 μm has been realized. Both a-cut and c-cut crystals are used. The output single-pulse energy the pulse width versus pump for different initial transmissions of V3+:YAG absorbers measured. experimental results show that, can generate shorter higher in comparison to one.
The deepening of globalization has facilitated the mingling and clashing different cultures. More more young people are in educational context multiple Adolescence is considered a critical period for developing self-identity. However, due to complexity cross-cultural education specificity adolescents psychological development, development self-identity will face significant challenges. Therefore, helping develop sense become one key issues field education. This study focuses on domain...
By considering both the transversal and longitudinal Gaussian spatial distribution of intracavity photon density, a couple rate equations describing laser-diode end-pumped passively Q-switched Nd:GdVO4 laser with V3+:YAG saturable absorber have been proposed. Solving these space-dependent numerically, we obtain dependences pulse width, repetition rate, single-pulse energy peak power on pump power. In experiment, by has realized, experimental results are consistent theoretical calculations.
By simultaneously using both an acoustic-optic (AO) modulator and a V3+:YAG saturable absorber in the cavity, for first time to our knowledge, diode-pumped doubly Q-switched Nd:GdVO 4 laser has been realized. The dependence of pulse width, energy peak power on incident pump at determinate repetition rate are measured. Under absorbed 8.59 W, temporal profile AO-switching with duration 14.5 ns, double Q-switching 7.6 ns 10 kHz, passive 22.3 obtained. is obviously compressed contrast purely...
The high degradation rate limits the clinical applications of calcium silicate bioceramics. In this paper, Ca2MgSi2O7 and Ca2ZnSi2O7 were successfully prepared using sol-gel method by incorporating magnesium zinc into Ca–Si-based system. results showed that obtained ceramics presented macroporous structure incorporation obviously reduced samples specific surface area. Compared with CaSiO3 (24.8%), weight loss was lowest (8.4%) middle (12.1%) after 28 days soaking in Tris-HCl buffers....
Comparisons are drawn between spatially resolved absorption spectroscopy data obtained for a 6.4kW dc arc jet reactor, operating with Ar∕H2∕CH4 gas mixtures, used deposition of thin, polycrystalline diamond films, and the results two-dimensional (r,z) computer model incorporating activation, expansion into low pressure chemistry neutral charged species. The experimental measurements, using either cavity ring-down or diode laser spectroscopy, determined absolute number densities H(n=2) atoms,...
Dosimetric measurements and monitoring play an essential role in radiotherapy. Because of their sensitivity relatively flat energy response ionization chambers remain the most important dosimeters. However, usually have large physical dimensions require high bias voltages to achieve acceptable collection efficiency. Such disadvantages limit applications for vivo dose measurements. The availability novel materials such as carbon nanotubes (CNTs) has created potential miniaturize traditional...
By using a new saturable absorber V3+:YAG, flash-lamp-pumped passively Q-switched Nd:YAG laser at 1.32 μm has been realized. The single-pulse energy and the pulse width of output versus pump are measured. With cavity length 440 mm 43.4 J, obtained 10 mJ 86.9 ns, respectively, corresponding to peak power 115 kW.
Using a V3+:YAG saturable absorber, we realize the running of laser-diode end-pumped passively Q-switched intracavity-frequency-doubling Nd:GdVO4/KTP red laser.

By simultaneously using both a V3+:YAG and Co2+:LaMgAl11O19 saturable absorber in the cavity, for first time to our knowledge, diode-pumped doubly Q-switched Nd:GdVO4 laser has been realized. The dependence of pulse width, repetition rate, energy peak power on incident pump are measured. Under absorbed 8.59 W, temporal profile passive double-switching with width 25.29 ns, single-switching just 30.46 ns obtained. duration is partly compressed contrast purely passively V3+:YAG.
