Abstract
An optically pumped semiconductor laser is assembled in an enclosure comprising a base, a first mounting frame attached to the base, a second mounting frame attached to the first mounting frame and a cover attached to the second mounting frame. The assembly base, frames, and cover forms an undivided enclosure, with the frames contributing to walls of the enclosure. Components of the laser are assembled sequentially on the base and the frames. The frames are irregular in height to permit flexibility in the mounting-height of components. This reduces the extent to which compactness of the enclosure is limited by any one component.

Optical apparatus, the optical apparatus including a plurality of components and being contained in an enclosure comprising:
- a base-member, configured to provide a floor of the enclosure;
- one or more open frame-members stacked on the base-member and forming walls of the enclosure;
- a cover-member covering the enclosure;
- and
- wherein at least one of the components of the apparatus is mounted on a frame-member.
Optical apparatus, the optical apparatus including a plurality of optical components comprising:
- a housing having an undivided internal volume, and containing the optical system, the housing including a rigid base, a rigid wall, with at least one the optical components being mounted on the rigid wall.
A method of assembling an optically pumped semiconductor (OPS) laser, said OPS laser including a semiconductor chip mounted on a first end mirror, a laser diode array for pumping the semiconductor chip, wherein said semiconductor chip is located within a resonator that includes the first end minor associated with the chip and a spaced apart second end minor and further including a birefringent filter and a non-linear crystal, said resonator being folded by a dichroic minor, said method comprising the steps of:
- mounting the laser diode array and the semiconductor chip on a rigid base;
- mounting a first rigid frame to the rigid base, said first rigid frame having four walls;
- mounting the birefringent filter to one of the walls of the first rigid frame;
- mounting a second rigid frame to the first rigid frame said second rigid frame having four walls;
- and
- mounting the non-linear crystal, second end minor and dichroic mirror each to a different wall of the second rigid frame.
