  "description": "Two methods of preparation of the devices for visualization of pulsed and continuous near-IR (near infrared) are described and the results of conversion of pulsed and continuous IR (800-1360 nm) laser radiation into the visible range of spectra (400-680 nm) by using a transparent substrate covered with the particles (including nanoparticles) of effective nonlinear materials of GaSe (x) S(1 - x) (0.2 a parts per thousand currency sign x a parts per thousand currency sign 0.8) are presented. Converted light can be detected in transmission or reflection geometry as a visible spot corresponding to the real size of the incident laser beam. Developed device structures can be used for checking if the laser is working or not, for optical adjustment, for visualization of distribution of laser radiation over the cross of the beam and for investigation of the content of the laser radiation. Low energy (power density) limit for visualization of the IR laser pulses with 2-3 ps duration for these device structures are: between 4.6-2.1 mu J (3 x 10(-4)-1 x 10(-4) W/cm(2)) at 1200 nm; between 8.4-2.6 mu J (4.7 x 10(-4)-1.5 x 10(-4) W/cm(2)) at 1300 nm; between 14.4-8.1 mu J (8.2 x 10(-4)-4.6 x 10(-4) W/cm(2)) at 1360 nm. Threshold damage density is more than 10 MW/cm(2) at lambda = 1060 nm, pulse duration tau = 35 ps. The results are compared with commercially existing laser light visualizators.",
