Study of laser ablation using nano-second laser pulses
In this paper, the laser ablation process based on the irradiation of nanosecond pulsed lasers on a copper target surface in the presence of Helium gas is studied. The dynamical behaviors of the generated plasma in the helium gas and evaporated copper at the atmospheric pressure are examined using a laser pulse, laser wavelength of and intensity of 7×1010W/cm2. A one-dimensional thermal model ...
متن کاملUse of Pulsed Photoacoustic Technique for the Study of Nonlinear Processes in Liquids
Pulsed photoacoustic measurements have been carried out in toluene, benzene and carbon disulphide liquids using 532 nm radiation from a Q-switched frequency doubled Nd:YAG laser. The present chapter deals with the detection and analysis of the photoacoustic effect in certain organic liquids in the visible region. The variation of photoacoustic signal am plitude with incident laser power indica...
متن کاملPulsed photoacoustic technique to study nonlinear processes in liquids: Results in toluene
Abstract. Pulsed photoacoustic measurements have been carried out in toluene at 532 nm wavelength using a Q-switched frequency doubled Nd:YAG laser. The variation of photoacoustic signal amplitude with incident laser power indicates that at lower laser powers one photon absorption takes place at this wavelength while a clear two photon absorption occurs in this liquid at higher laser powers. Th...
متن کاملProduction of Alumina Nanoparticles (Al2O3) using Pulsed Laser Ablation Technique in Distilled Water Solution
Pulsed Laser Ablation in Liquid (PLAL) has become an increasingly important technique for metals production and metal oxides nanoparticles (NPs). This technique has its many advantages compared with other conventional techniques (physical and chemical). This work was devoted for production of alumina (Al2O3) nanoparticles via PLAL technique from a solid alumina target immersed in Distilled Wate...
متن کاملGenerating photoacoustic signals using high-peak power pulsed laser diodes
Photoacoustic signals are usually generated using bulky and expensive Q-switched Nd:YAG lasers, with limited scope for varying the pulse repetition frequency, wavelength and pulse width. An alternative would be to use laser diodes as excitation sources; these devices are compact, relatively inexpensive, and available in a wide variety of NIR wavelengths. Their pulse duration and repetition rate...
