We show theoretically and experimentally how the damping of the relaxation oscillations is reduced and finally becomes zero when the pump power is reduced so that the threshold for Q-switched mode locking is approached. For the first time to our knowledge, this method provides important information...
5.1. It is seen that the carrier density at the front of the pumping pulse passes the threshold value at a certain time t0, at which point the net gain in the laser becomes positive and the photon density starts growing from a small seed provided by the spontaneous emission. However, ...
Our acousto-optic modulators are optimized for low scatter and high laser damage threshold. Rise time, modulation rate, beam diameter, and power handling needs of the application need to be understood in order to identify the best acousto-optic modulator and RF driver solution. We also offer fib...
Second threshold condition in the case of Q switching by self-focusing In a recent paper (Opt. Lett. 10,, 402 (1985)) we presented a novel passive technique for obtaining giant laser-pulse emission. In this paper we present a ... MC Marconi,OE Martinez,FP Diodati - 《Journal of the ...
Because of its chemically stable, durable, UV resistant, good thermal conductivity and high damage threshold (> 500 MW/cm2) and being easy to be operated, it will replace traditional materials, such as, LiF, organic Dye and color centers. Manufacturing accu...
(here corresponding to ≈0.8 eV) the saturable absorption is mostly attributed to the bulk states. High modulation depth of the device together with high damage threshold makes it very suitable for the application as a modulator in passively Q-switched lasers. The same measurement has been ...
What is DCM / CCM versus FCCM and what are the advantages of each? How is the inductor selected for controllers and regulators? Where should the programmed overcurrent threshold Iocp be set? How does Discontinuous Conduction Mode (DCM) increase efficiency at light loads? Company...
When the voltage at the VCC pin exceeds the Vcc UVLO threshold of 5.35V and the SD pin is greater than 1.225V, the output switch is enabled and a soft-start sequence begins. The output switch remains enabled until Vcc falls below 5.0V or the SD pin falls below 1.125V. An auxiliary ...
