    摘要: A lasing wavelength is controlled so that a wavelength detection result becomes a first target value; selection is made to select either a step of calculating a second target value as a wavelength detection result with a shift of the lasing wavelength, or a step of calculating a third control value of a wavelength characteristic of an etalon for letting a laser lase at a wavelength with a shift of the lasing wavelength; in the former step, the lasing wavelength is controlled so that the wavelength detection result becomes the second target value; in the latter step, the lasing wavelength is controlled so that the wavelength detection result becomes the first target value.

    摘要: The disclosure relates to method and apparatus for micro-contact printing of micro-electromechanical systems (“MEMS”) in a solvent-free environment. The disclosed embodiments enable forming a composite membrane over a parylene layer and transferring the composite structure to a receiving structure to form one or more microcavities covered by the composite membrane. The parylene film may have a thickness in the range of about 100 nm-2 microns; 100 nm-1 micron, 200-300 nm, 300-500 nm, 500 nm to 1 micron and 1-30 microns. Next, one or more secondary layers are formed over the parylene to create a composite membrane. The composite membrane may have a thickness of about 100 nm to 700 nm to several microns. The composite membrane's deflection in response to external forces can be measured to provide a contact-less detector. Conversely, the composite membrane may be actuated using an external bias to cause deflection commensurate with the applied bias. Applications of the disclosed embodiments include tunable lasers, microphones, microspeakers, remotely-activated contact-less pressure sensors and the like.

    摘要: In certain embodiments, a system (10) comprises a laser source (20), one or more optical elements (24), a monitoring device (28), and a control computer (30). The laser source (20) emits one or more laser pulses. The optical elements (24) change a pulse length of the laser pulses, and the monitoring device (28) measures the pulse length of the laser pulses to detect the change in the pulse length. The control computer (30) receives the measured pulse length from the monitoring device (28), determines one or more laser parameters that compensate for the change in the pulse length, and controls the laser source (20) according to the laser parameters.
