چکیده مقاله:

This paper describes the passive Qswitch, based on polymer and organic dye BDN, of a pulsed Nd:YAG laser. Pulses of 27ns duration and peak power of 1.7MW for initial transmission of Q-switch 18.4% 0 T = have been obtained. We have obtained Q-switching efficiency of 77% for train of pulses of 31 and 76.2% 0 T = at the pump energy of 98J. We have also obtained the dependency of laser pulse characteristics on pump energy and initial transmission of Q-switch. We have obtained the damage threshold of this Q-switch at the pulse duration of 27ns to be13J cm2 .

Clinical applications of Q-switched NdYAG laser.

682 infrared range of the electromagnetic spectrum. Though all these lasers would have some effect on melanin, three wavelength bands are most useful for treating pigmented lesions – green, red, and infrared.[1] Its not only about the wavelength, it is more about the right pulse duration and at sufficient fluence. Since green and blue light lasers are long pulsed continuous waves, they cause a ...

Pulsed Solid State Laser with Passive Q-switch

In this seminar we present the structure, operating regime and use of solid state laser with passive Qswitch. We give a description and comparison of two basic concepts of optical pumping, the lamp pumping and the diode pumping. Finally we present the Q-switch theory and more precisely passive Q-switch theory.

Picosecond laser pulse generation in a monolithic self-Q-switched solid-state laser

We report the generation of laser pulses of 290-ps duration with 8-N pulse energy in single longitudinal mode and single transverse mode in a diode-end-pumped monolithic self-Q-switched Cr,Nd:YAG laser. The most commonly used method of generating picosecond laser pulses is the mode-locking technique. Mode-locking generally requires a light modulator such as an intracavity acousto-optical modula...

Time Frequency Analysis of Higher Harmonic Generation in a Three Color Laser Pulse

high harmonic generation is a useful tool for the generation of short, intense attosecond pulses. In order to simulate high harmonic generation, we performed a numerical solution to the time dependent Schrödinger equation. by considering dipole approximation, we predicted generation of a 53 attosecond pulse. In order to see the time and frequency of emission of attosecond pulse, we exploit...
