Abstract: A CW laser with a rotating ring gain element is disclosed. The ring is pumped at multiple locations and the laser generates a mid-IR output. Multiple pumped gain portions of the ring provide a power scaled output. The gain portions may be positioned in a single resonator cavity, in multiple resonator cavities, and in MOPA architectures with associated focusing, folding, and combining optical elements.

Abstract: The present invention provides systems and methods for producing short laser pulses that are amplified and spectrally broadened in a bulk gain media. The bulk material, having laser gain and nonlinear properties, is concurrently exposed to an optical pump input and a seed input, the pump power being sufficient to amplify and spectrally broaden the seed pulse.

Abstract: Systems and methods for spectrally broadening seed pulses with a single pass laser amplifier are disclosed. A bulk TM:II-VI polycrystalline material with combined gain and nonlinear characteristic provides passive (cold) spectral broadening of high power seed pulses. Continuous pumping provides more significant spectral broadening. In particular, pulsed pumping of TM:II-VI polycrystalline material (e.g. Cr2+:ZnS, Cr2+:ZnSe, and Cr2+:CdSe) is shown to provide significant spectral broadening to the super continuum generation SCG level. Pulse picking, pump sources, master oscillators and various optical components are described.
