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.

An optical scanning or positioning mechanism has a head on which optical components are mounted and an actuator coupled to the head to cause the head to move when the actuator is actuated. There are one or more sets of flexure bearings mounted in the mechanism. The flexure bearings have a restoring torque when moved from a rest position. The bearings are coupled to the head to allow the head to move when actuated by the actuator. One or more magnets are mounted in the mechanism in a location other than in the actuator to compensate for the flexure bearings restoring torque.
