Power Scaling of Solid State Lasers

Approach for power scaling solid-state lasers with intracavity motion.

Solid-state lasers are typically limited by adverse thermal effects within the gain medium. In this Letter we describe a new method for dramatically reducing thermal effects in an end-pumped solid-state laser by incorporating a rotating intracavity periscope in the resonator to spatially separate the lasing and thermal processes. In contrast with previous examples of moving solid-state lasers, ...

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...
