An optical system including a gain material pumped by pump energy bands delivered to the gain material from different directions and separated sufficiently to prevent crosstalk between pump energy sources. Embodiments of the pump energy sources may be configured to pump the gain material with pump energy bands that correspond to absorption bands of the gain material.

Single layer, fluidic polymer-based coatings are provided for application or deposition onto a target surface of a photonic device, whereby the coating is formed of one or more spectral tuning materials so as to absorb infrared, ultraviolet or infrared and ultraviolet wavelength that might otherwise be present as background and would interfere with the performance of the photonic device in optical applications.

A Process and device for displacing a moveable unit on a base.The process includes:a) a force (F) is determined which, applied to the moveable unit (4), produces a combined effect, on the one hand, on the moveable unit (4) so that it exactly carries out the envisaged displacement on the base (2), especially as regards the prescribed duration and prescribed distance of the displacement, and, on the other hand, on the elements (MA1, MA2, MA3, 4) brought into motion by this displacement so that all these elements are immobile at the end of said displacement of the moveable unit (4);andb) the force (F) thus determined is applied to the moveable unit (4).

Intermittent stabilization of a load table supported by pneumatic vibration isolators is provided by determining a load shift condition, increasing passage of gas to the pneumatic vibration isolators and imposing external or internal damping on the load table in response to that load shift condition. For internal damping, the pneumatic vibration isolator is provided with damping fluid in one of its pneumatic chambers and a damping fluid friction passage is provided between that damping fluid in that one pneumatic chamber and the other pneumatic chamber.

Method and apparatus for mode coupling a light beam into an optical cavity having a cavity axis, effect reflection of light of that beam with a mirror along a geometric ray originating laterally of the cavity axis. The mirror is rigidly interconnected with the cavity and is adjusted until the geometric ray coincides with the light beam. That geometric ray is retained in space while moving the optical cavity so that the cavity axis moves translatorily relative to the retained geometric ray, until the cavity axis coincides with the retained geometric ray and thereby with the light beam. Where an optical cavity is located in an oven, first temperature variations of a wall of that oven and second temperature variations of the cavity are sensed, and energization of the oven is controlled more rapidly in response to these first temperature variations, than in response to those second temperature variations.
