Solid State Lasers for Stereolithography

Stereolithography is a Rapid Prototyping & Manufacturing (RP&M) technique which is used to produce 3 dimensional plastic parts directly out computer files generated by CAD. Stereolithography systems use ultraviolet lasers to solidify liquid resin into the desired form as defined by the CAD file. In recent years, solid state laser technology has reached the point where it can be applied to stere...

Low-heat Solid-state Lasers

The paper discusses the processes that determine the parasitic heat generation and its distribution in the solid-state laser materials. It is inferred that the balance between the laser emission and heat generation is determined by the characteristics of the pumping system and by the partial efficiencies of the various steps of the flow of excitation between the energy levels of the laser mater...

Agile solid state dye lasers

Different organic dye molecules were incorporated in solid gels by the sol gel process with a view to develop tunable solid state laser applications. We studied the laser emciency of these materials by using a nanosecond frequency doubled Nd:YAG as the pump laser. Slope emciency up to 30 % with 3 mJ output energy and half energy lifetime of 40,000 shots were thus obtained. This large lifetime w...

Diode-Pumped Solid State Lasers

III The use ofdiode lasers instead ofHashlamps as optical pump sources for solid state lasers offers significant advantages such as higher efficiency and longer lifetime. We have demonstrated three novel lasers based on this technology. The first is a zig-zag slab laser pumped by hybrid planar microchannel-cooled diode arrays that allow high-repetition-rate operation in a pulsed mode. The secon...
