Abstract
Za promatranje interakcije nanosekundnog laserskog ultraljubičastog snopa s metalnim površinama koristio se impulsni dušikov laser valne duljine laserskog snopa λ=337 nm, trajanja impulsa t=6 ns i maksimalne gustoće energije 0,6 J/cm2. Kao mete korišteni su različiti metali (aluminij, indij, niobij i molibden) koji su stavljani u žarište laserskog snopa, u zraku i pri normalnom atmosferskom tlaku. Spektralne linije plazme proizvedene pri udaru laserskog snopa u metalnu površinu analizirane su pomoću monokromatora, fotomultiplikatora i digitalnog osciloskopa. Mjerenja su omogućila određivanje temperature elektrona u plazmi. Izračunate vrijednosti su 1,5 eV (17400 K) za aluminij, 1,7 eV (19700 K) za indij te 1,3 eV (15000 K) za niobij i molibden. Nastala oštećenja na površinama metala proučavana su pomoću metalografskog mikroskopa, pretražnog elektronskog mikroskopa i uređaja s fokusiranim ionskim snopom.
Abstract (english)
A pulse nitrogen laser, emitting pulses of 6 ns duration with an average energy density of 0.6 J/cm2 and wavelength of 337 nm was used for observing interaction of nanosecond ultraviolet laser beam with metal surfaces. Various metal targets (aluminium, indium, niobium and molybdenum) were placed in focus of laser beam, in the air at normal atmospheric pressure. Plasma spectral lines, developed by laser beam impact on metal surface, were analyzed by means of monochromator, photomultiplier and digital oscilloscope. Calculation of plasma electron temperature was enabled with those measurements. Calculated values were 1.5 eV (17400 K) for aluminium, 1.7 eV (19700 K) for indium and 1.3 eV (15000 K) for niobium and molybdenum. Created damages on metal surfaces were observed by means of a metallographic microscope, a scanning electron microscope (SEM) and a focused ion beam (FIB) device.
