چکیده

Pulses from a broadband dye laser operating in many modes have been temporally smoothed by passing them through a strongly saturated dye amplifier in the presence of a strong, nonsaturable absorber. The standard nonlinear coupled partial differential equations based on the rate-equation approximation have been used to model the amplifier. Both analytic and numerical solutions for the equations show that under attainable conditions the intensity of the amplified pulse follows the temporal shape of the pump pulse.

The Degree of Temporal Synchronization of the Pulse Oscillations from a Gain-Switched Multimode Semiconductor Laser

Langevin noise leads to inhibition of the temporal synchronization of the pulse oscillations from a gain-switched multimode semiconductor laser, resulting in the power reduction in optical beat detection. In this paper, the degree of the temporal synchronization of the pulse oscillations was examined by numerically estimating the output energy in THz time-domain spectroscopy (THz-TDS) using mul...

Tunable all-fiber dissipative-soliton laser with a multimode interference filter.

We report on a tunable all-fiber dissipative-soliton laser with a multimode interference filter that consists of a multimode fiber spliced between two single-mode fibers. By carefully selecting the fiber parameters, a filter with a central wavelength at 1032 nm and a bandwidth of 7.6 nm is constructed and used for spectral filtering in an all-normal-dispersion mode-locked ytterbium-doped fiber ...

1.7MW Nd:YAG Laser Pulse Generation by A Passive BDN Q-switch

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 charac...

Tunable, High-Power, Subpicosecond Blue-Green Dye Laser System with a Two-Stage Dye Amplifier

A two-stage dye amplifier design has been developed to amplify tunable, blue-green, subpicosecond dye laser pulses which are generated from a hybrid synchronously modelocked dye oscillator directly (800 fs) or shorter to 200 fs by a fiber compressor stage. This system has achieved single pulse energies of 2 mJ, with an amplified spontaneous emission content of less than 0.1%. Using 40 mJ of the...
