In this paper, we study the oxidation process during the heating of a titanium metallic surface by a Nd-YAG fiber pulsed laser beam under air environment. For this, we adopted an approach that considers a three-dimensional heat diffusion model couple

In this communication we deal with a lidar system utilising an eye safe laser wavelength at 1.57 μm and an avalanche photodiode detector where it is question to optimize the SNR ratio so as to manage the detector performance when resolving the smoke

The power supply of flash lamp‐pumped solid‐state lasers (such as ND: YAG Laser) basically consists of a trigger circuit, a simmer circuit and the main discharge circuit. All of which are synchronized by a command circuit. To reduce both size and

In order to optically pump pulsed solid‐state lasers like Nd: YAG laser, one needs a power supply that basically contains a trigger circuit, a main discharge circuit and a simmer circuit. These circuits must be synchronized by a command. In this co

Flash lamp pumping of pulsed solid‐state lasers, such as Nd:YAG laser needs a power supply that contains three main parts: the trigger circuit, the main discharge circuit, and the simmer circuit. The operation of these circuits must be synchronized

In lasers, the use of diffracting apertures involves many effects and applications. This goes from the selection of only one eigenmode to oscillate inside the resonator, often called the fundamental mode, the discrimination of the opposite travelling
