Abstract: A method of spectrally multiplexing diode pump modules to increase brightness includes generating one or more pump beams from respective diode lasers at a first wavelength in a diode laser package, generating one or more pump beams from respective diode lasers at a second wavelength different from the first wavelength in the diode laser package, wavelength combining at least one of the pump beams at the first wavelength with at least one of the pump beams at the second wavelength to form one or more combined pump beams, and receiving the combined pump beams in a pump fiber coupled to the diode laser package. Laser systems can include multi-wavelength pump modules and a gain fiber having a core actively doped so as to have an absorption spectrum corresponding to the multiple wavelength, the gain fiber situated to receive the pump light and to produce an output beam at an output wavelength.

Abstract: Aspects of an optical communications network are described that include two or more optical fibers arranged to allow communication in the same or in opposite directions. The optical network includes a first optical amplifier coupled to the first optical fiber, a second optical amplifier coupled to the second optical fiber, and an optical coupler that allows excess optical power from the first optical fiber to be provided for amplification of signals traversing the second optical fiber. The disclosed systems and devices thus enable excess power from one channel to be utilized to enable amplification of signals traveling on a different channel.

Abstract: An optical crystal can be mounted to a mounting block configured to receive the crystal. A base portion on the mounting block utilizes two walls forming a corner and a single biasing spring clip to secure the crystal. The spring clip applies forces in two different directions substantially orthogonal to the two walls. The spring clip is based off a symmetrical geometry which applies nearly the same force application in both directions. The spring also features bend regions that contact the crystal in such a way as to reduce the presence of point loads or stress risers. The length of contact along the crystal is maximized, allowing for proper force distribution and a sufficient surface are contact for static holding capabilities.
