Cascaded Nonlinear Optical Mixing in a Noncollinear Optical Parametric Amplifier
Ultrafast optical science is a rapidly evolving multidisciplinary field: the ability to excite matter with femtosecond light pulses and probe its subsequent evolution on ultrashort time scales opens up completely new fields of research in physics, chemistry, and biology.[1] Furthermore, the high intensities that can be generated using femtosecond light pulses allow us to explore new regimes of ...
متن کاملParametric Performance Analysis of 2-GHz Low Noise Amplifier
In this paper designed, implemented and simulated LNA is divided into two parts. In the first part, LNA is based on lumped elements and in second part LNA is based on distributed elements. Two designed methods have been compared and best performance is obtained with lumped elements. The designed amplifier provides a noise figure of 0.358 dB , gain of 16.778 dB, input return loss is -4.917dB and...
متن کاملA low-noise series-array Josephson junction parametric amplifier
We have obtained parametric gain at 19 GHz from a distributed Josephson junction parametric amplifier whose active gain medium consists of a series array of 1000 Josephson junctions embedded in a coplanar waveguide. When cooled to 1.7 K the amplifier provides 16 dB gain in a mode where the internally generated double sideband noise referred to input is 0.560.1 K. This noise is consistent with N...
متن کاملBroadband light generation by noncollinear parametric downconversion.
Broadband light generation is demonstrated by noncollinear spontaneous parametric downconversion with a cw pump laser. By use of a suitable noncollinear phase-matching geometry and a tightly focused pump beam, downconverted signals that feature a bell-shaped spectral distribution with a bandwidth approaching 200 nm are obtained. As an application of the generated broadband light, submicrometer ...
متن کاملThe Lock-In Amplifier: Noise Reduction and Phase Sensitive Detection
To see how our Project Lock-In works, have a look at the Schematic I. You will find there the internal electronic components of the instrument and their interconnections. The most essential parts to make the Lock-In work as such, are a multiplier circuit and a low pass circuit, or integrator, which together form a “PhaseSensitive Detector", or PSD. For reasons you will immediately understand, a...
