The OPO's tuning ranges at the doubly and singly resonant forms tuned with temperature were 844.l-1411.3nm and 738.9-1032.2nm and the minimum pump thresholds were 0.22mJ/pulse and 0.66mJ/pulse, respectively.
When the input signal and the first control wavelengths are kept at 1554.2 nm and 1532.5 nm,respectively,the output signal wavelength can be tuned from 1536.0 nm to 1545.2 nm as the second control wavelength is varied from 1550.5 nm to 1541.0 nm.
The development of the Cr~(4+)–doped crystals and successful working of pertinent lasers extend the tune of solid tunable lasers from 0.7μm～1.0μm generated by Cr~(3+) and Ti~(3+) ions to 1.0μm～1.8μm ,so the study of them has become the hot pot of the study of solid tunable lasers.

The converter achieves a zero-current tuning off for inner switching, and a zero-voltage tuning on for outer switching.
A nonlinear proportion integration differentiation (PID) controller is proposed on the basis of recurrent neural networks, due to the difficulty of tuning the parameters of conventional PID controller.
Variable identification and automatic tuning of the main module of a servo system of parallel mechanism
These results demonstrate the role of hydrogen bonds in molecular assembly formations and what is more, would be beneficial for understanding and fine tuning of the assembling of truxene-related opto-electronic materials.
Thus, frequencies can be modulated by modifying the local construction of the rotor to make the natural TV frequency of a certain order avoid some specific value, herewith arriving at the objective of tuning.
The proof relies on a family of inversion formulas for the Segal-Bargmann transform, which can be "tuned" to give the best estimates for a given value of p.
The most important feature of the proposed scheme lies in that it can be explicitly tuned with a single parameter for the trade-off between performance and stability of the AQM control system.
The variables of the main module of a servo system for miniature reconfigurable parallel mechanism were identified and automatically tuned.
The multiple tuned mass damper (MTMD) system is applied to control vertical bending buffeting response.
A new semiactive lever-type tuned mass damper (TMD) with an adjustable frequency is proposed to control vertical bending buffeting and torsional buffeting and flutter in the whole velocity range of bridge decks.
The CdSe NCs obtained which show a good PL property are monodisperse, size-tunable and of high crystallinity.
A Fast Tunable Detector of Submillimeter Waves on Cyclotron Resonance in an InSb Crystal
The detector reception band is tunable between 80 and 250 μm (3.75-1.2 THz).
This system employs tunable ferrite-loaded cavities and is encircled by six feedback loops (both dedicated and spurious) with a cross-talk through a heavy beam loading, high accelerating rate, and the overlapping of the loop passbands.
They ensure the formation of highly coherent double laser pulses with a tunable time between them upon a single photoelectrically initiated turning on of an active shutter and using a bleachable filter.
The multilayer construction of the waveguide, in combination with specially shaped ferroelectric-permittivity-controlling electrodes, allows designers to tune the spectrum of the waveguide and suppress electron-bunch-deflecting waveguide modes.
Special choices of Dirichlet and Robin type boundary conditions can be used to tune up such bioswitches.
Instead, one just needs to tune the wavelength of one mixing beam within the bandwidth of as narrow as 15.3 nm.
The paper introduce the measurement of some beam parameters for Hefei Light Source (HLS) by frequency domain technique, which include the betatron tune, average beta function, natural chromaticity, corrected chromaticity, and center frequency.
Additionally, the measurement of the influence of DC clearing electrodes on the betatron tune shift is also described.
