    Abstract: Techniques and architecture are disclosed for providing a laser system. In one specific example embodiment, the system includes a thulium-doped fiber laser coupled by silica glass fiber to a remote optical converter (ROC) including a Ho:YAG laser and, optionally, an optical parametric oscillator (OPO) utilizing in germanium phosphide (ZnGeP2; ZGP) or orientation-patterned gallium arsenide (OPGaAs). The fiber laser may emit a low-peak-power, continuous wave pump signal that pumps the Ho:YAG laser, which in turn emits a higher-peak-power, pulsed signal. When included, the OPO can be used to convert the resultant, pulsed signal to a longer wavelength (e.g., about 2-5 μm, or greater). In some cases, distributed architecture and reduced weight/bulk may be realized while eliminating the need to actively cool the ROC for operation, for example, over a broad temperature range (e.g., −55-125° C.). Also, methods of preparing high-peak-power, pulsed signals using such systems are disclosed.

    Abstract: A system and method for passing a fiber cable through a fiber connector is presented. A fiber connector includes an outer body and a series of flutes inside the outer body. The outer body forms an interior chamber that has a first opening and a second opening. The first opening allows a coolant to flow into the first opening and the first and second openings allow the fiber cable to pass through the first opening and the second opening and through the fiber connector. A series of flutes are attached to an inner surface of the outer body and extend into the interior chamber. The flutes are spaced apart from each other and extend from the inner surface toward the fiber cable but do not touch the fiber cable when no liquid is flowing in the fiber connector.
