Abstract-Solar pumped laser (SPL) can find wide applications in space missions, especially for long lasting ones. In this paper a new technological approach for the realization of a SPL based on fiber laser technology is proposed. We present a preliminary study, focused on the active material performance evaluation, towards the realization of a Nd 3+ -doped fiber laser made of phosphate glass materials, emitting at 1.06 μm. For this research several Nd 3+ -doped phosphate glass samples were fabricated, with concentration of Nd 3+ up to 10 mol%. Physical and thermal properties of the glasses were measured and their spectroscopic properties are described. The effect of Nd 3+ doping concentration on emission spectra and lifetimes was investigated in order to study the concentration quenching effect on luminescence performance.

Passive Q-switched laser at 1064 nm with an average power of ranges from 0.5 W to 3.25 W using Cr:YAG [11,[14][15][16] initial transmission of 30% as in Figure 19, pulse repetition rate ranges from 45 kHz to 400 kHz. Figure 20(a), pulse width ranges from the shortest one of 4 ns to the largest pulse width of 250 ns at FWHM using initial transmission of 40% and 70%, and increased to 3 power of 2 W, as seen in and peak power at certain mode of operation for limited pump power range m 13 kW to 18 kW using 70% and 30%, respectiv re investigated and The time characteristics of the highest and fast passive Q-switched laser pulses were measured with the help of a fast vacuum photodiode (Thorlab Inc. model PDA10C) and Tektronix oscilloscope TDS 3052B (200 MHz, 2 GS/s).…”

Diode end-pumped solid-state lasers have the potential to yield high quality laser beams with high efficiency for laser range finding and warning receiver applications as well as day and night military laser designation systems. In this paper we presents theoretical calculations using Advanced Dynamics Professional LASCAD software and experimental studies for a high power pigtailed fiber diode laser module of 8 W operating at 808 nm with a specially designed high efficiency cooling system, end pumped high-efficiency Nd:YVO 4 laser of 3 × 3 × 10 mm rod and overall cavity length of 44 mm. To the best of our knowledge a self Q-switching effects was generated in Nd:YVO 4 laser by changing the cavity dimensions and the position of the intracavity KTP crystal at certain regime of operation for the first time, in which the cavity length is reduced to be 30 mm and the distance between Nd:YVO 4 rod and KTP crystal is only 1mm. Self Q-switched laser pulse at 532 nm with high peak power of 96 W, pulse width of 88 ns at FWHM and repetition rate of 400 kHz was achieved. Experimental studies of a passive Q-switched Nd:YVO 4 laser using Cr:YAG crystal with three different transmissions of 30%, 40% and 70% were investigated. Passive Q-switched laser pulse at 1064 nm and narrow line width of less than 1.5 nm with highest peak power of nearly 18 kW, short pulse width of less than 4 ns at FWHM and higher repetition rate of 45 kHz using Cr:YAG with transmission of 30% was achieved for the first time.
