“…Side pumping of slab geometry lasers offers scaling to high average power levels because the power scales as the area of the slab. Although early results on diode array pumping of slab Nd:YAG by the Livermore group reported only 70W of average power 87 recent results have been reported at the llOOW average power level. This is the highest average power reported from a diode laser array pumped solid state laser.…”

“…The assembly used for this experiment was built to pump a high avcrage power solid state laser (Comaskey, 1992) and had previously been measured to operate at up to 578 watts at an operating point of 60 A and 43.1 V, for an efficiency (DC to optical power) of 22.4% (Mitchell, 1997). Similar arrays operate at efficiencies as high as 45 -50%.…”

Abstract. A preliminary demonstration of free-space electric power transmission has been conducted using non-coherent laser diode arrays as the transmitter and standard silicon photovoltaic cell arrays as the receiver. The transmitter assembly used a high-power-density array of infrared laser diode bars, water cooled via integrated microchannel heat sinks and focused by cylindrical microlenses. The diode array composite beam was refocused by a parabolic mirror over a 10 meter path, and received on a -1.5 x 25 cm panel of thinned single crystal high efficiency silicon solar cells. The maximum cell output obtained was several watts, and the cell output was used to drive a small motor. Due to operating constraints and unexpected effects, particularly the high nonuniformity of the output beam, both the distance and total received power in this demonstration were modest. However, the existing transmitter is capable of supplying several hundred watts of light output, with a projected received electric power in excess of 200 watts. The source radiance is approximately 5 x lo9 W/m'-steradian. With the existing 20 cm aperture, useful power transmission over ranges to -100 meters should be achievable with a DC to DC efficiency of greater than 10%. Non-coherent sources of this type are readily scalable to powers of tens of kilowatts, and with larger apertures can be used directly for power transmission up to several kilometers. Future non-coherent diode laser sources may be suitable for power transmission over hundreds of kilometers. Also, the experience gained with non-coherent arrays will be directly applicable to power beaming systems using coherent diode arrays or other array-type laser sources.

“…The diode side-pumped solid-state laser is one of advanced lasers and being paid much attention in [1,2]. High laser efficiency can be obtained because there is a good spetial match between the emission spectrum of pump beam and the absorption spectrum of solid-state laser medium.…”

Abstract. The condition to match the pumped-volume's width with the laser mode-volume's waist in a diode four side pumped solid-state laser is analyzed by numeric solutions of the approximation equation. As a result, the dependences of pumped volume's width on pumping diode parameter and laser mode volume's waist on cavity parameter were found. Such a matching condition was simultaneously determined by cavity, pumping beam and laser rod parameters.
