چکیده
We present a high efficiency source of picosecond pulses derived from dual cavity optical frequency comb generator. This approach overcomes the limitations single generators that are restricted to efficiencies few percent. achieve with GHz repetition rates offering over hundred times higher output than design and demonstrate tuning pulse width by varying modulation depth intra-cavity electro-optic modulator. These results provide wavelength-agnostic compact footprint for development portable pulsed laser systems timing, metrology, LIDAR applications.

High Field, High Efficiency Terahertz Pulse Generation by Optical Rectification
The great difficulty of producing high intensity radiation in the terahertz (THz) spectral region by conventional electronics has stimulated interest in development of sources based on photonics. Optical rectification in lithium niobate is an attractive approach, because it supports high generation efficiencies, uses low cost, bulk LN crystals, and is powered by common Yb-doped lasers at wavele...
متن کاملHigh-Efficiency Resonant Cavity Quadrupole Moment Monitor
Measurement of the beam quadrupole moment at several locations can be used to reconstruct the beam envelope and emittance parameters. The measurements can be performed in a non-intercepting way using a set of quadrupole-mode cavities. We present a cavity design with an optimized quadrupole moment shunt impedance. The cavity properties can be characterized using a wire test method to insure symm...
متن کاملLinear optical properties of a high-finesse cavity dispersively coupled to a micromechanical membrane
We present measurements of an optomechanical system in which the mechanical element is inside the cavity, and couples dispersively to the intracavity field. This geometry makes it easier to simultaneously achieve high optical finesse and high mechanical quality factor in an optomechanical device. We measured the linear optical properties of a such a device in which the mechanical element is a 5...
متن کاملHigh finesse optical cavity coupled with a quartz-enhanced photoacoustic spectroscopic sensor.
An ultra-sensitive and selective quartz-enhanced photoacoustic spectroscopy (QEPAS) combined with a high-finesse cavity sensor platform is proposed as a novel method for trace gas sensing. We call this technique Intra-cavity QEPAS (I-QEPAS). In the proposed scheme, a single-mode continuous wave quantum cascade laser (QCL) is coupled into a bow-tie optical cavity. The cavity is locked to the QCL...
متن کاملHigh-efficiency multipass optical limiter.
We report experimental results on a highly efficient optical limiter that uses a three-mirror, multipass ring configuration. The optical limiter's enhanced performance is based on the accumulative effect that is achieved when the laser beam passes through the sample several consecutive times. Its feasibility was demonstrated for media with different limiting action processes, namely, reverse sa...
