Abstract: Apparatus for and methods of controlling wavelength in a system for producing laser radiation at more than one wavelength (color) in which one or more actuators control wavelength in response to being supplied with a waveform. The characteristics of the waveform, and/or of a controller for controlling the waveform, are determined based on a current repetition rate of the laser. A current repetition rate is determined and if it is new then a new waveform is commanded. Also disclosed is a system in which a correction depending on repetition rate is applied to an ILC algorithm determining a wavelength.

Abstract: The present disclosure is directed to systems and methods for controlling a center wavelength. In one example, a method includes estimating a center wavelength error. The method also includes determining a first actuation amount for a first actuator controlling movement a first prism based on the estimated center wavelength error. The method also includes actuating the first actuator based on the actuation amount. The method also includes determining whether the first prism is off-center. The method also includes, in response to determining that the first prism is off-center, determining a second actuation amount for the first actuator and determining a third actuation amount for a second actuator for controlling movement of a second prism. The method also includes actuating the first actuator and the second actuator based on the second and third actuation amounts, respectively. The method finds application in multi-focal imaging operations.

Abstract: Moisture and condensation barriers for protecting wood from damage in building structures (particularly but not necessarily in flooring systems) include a liquid rubberized coating material coated onto some of the wood or a barrier sheet having a petroleum-based tar layer.
