Abstract: Optical fiber filters and uses thereof are presented. In typical implementations, there is provided a FBG taking deleterious light out of a fiber core without reflecting it into the fiber core. It also allows the unhindered transmission of useful light at a wavelength outside of the spectral band covered by the deleterious light. The filter couples the incoming deleterious light to cladding modes propagating in the opposite direction without coupling the incoming useful light to core or cladding modes propagating in the opposite direction. The filter may for example be useful as a Raman or ASE filter in a laser cavity of other optical devices.

Abstract: A bulk compressor for use in a chirped pulse amplification system (CPA) comprising a tunable pulse stretcher and an amplifier is provided. The bulk compressor includes a mounting block formed as a monolithic structure and made of solid material. The mounting block may define a plurality of mounting surfaces each forming a collar surrounding a light passage. Optical components are mounted on the mounting block in a fixed mutual spatial relationship, each optical component having a front face having a peripheral portion mounted in direct contact with the collar formed by a respective one of the mounting surfaces. The bulk compressor may be provided as a stand-alone component, a part of a stretcher-compressor pair or a full CPA system, and may be used in a method for amplifying input optical pulses.

Abstract: A light pulse generator is provided, comprising a linear resonator cavity supporting the back-and-forth propagation of cavity light pulses therein. The linear resonator cavity has a linear optical path apt to induce a spectral broadening of the cavity light pulses. The light pulse generator includes first and second cavity-end filters disposed at opposite extremities of the linear optical path, and at least one optical gain region positioned in the linear optical path. A light output is optically coupled to the first cavity-end filter. The light pulse generator also includes a pulse-recycling filter optically coupled to the second cavity-end filter and having a reflectivity profile centered on a third wavelength. The pulse-recycling filter is configured to receive at least a spectral portion of the cavity light pulses and reflect recycled light pulses for a single pass through the at least one optical gain region and for extraction through the light output.
