frequency comb,and an average power of 4.5 kW is reached in the femtosecond enhancement cavity.With Xe gas as the working media,harmonics up to the 19th order are observed.Power measurement indicates that as much as 115.9渭W(1.3 mW)are generated at^94 nm(~148 nm).The shortest wavelength ...
Photon energies in the ERS are directly associated with specific wave properties such as frequency (ν) in Hz or cycles per second [cycles per s] and wavelength (λ) in meters (m). Wave properties are related according to Einstein's classic expression [1]E=hν=hc/λ where E is the ...

First, the dark current of the device was sampled and digitized by Keithley 2636B source meter in the time domain. Then, the noise power spectral density in the frequency domain was obtained by Fourier transform. A self-assembled vacuum spectral response testing system was applied to measure ...
A intra- cavity tripe frequency 355 nm ultraviolet laser with high power and high efficiency is reported. Type- II phase matching is used both in second harmonic generation and third harmonic generation.Polarization states of harmonic lasers are selected to improve the conversion efficiency from the...
A Cu–Sn–Zn–Pb alloy was irradiated by ultraviolet nitrogen laser pulses (N 2 laser, wavelength 337 nm, pulse duration 6 ns, frequency 1 Hz, power 0.5 MW... Franc Zupani,T Bon?Ina,Davor Pipi,... - 《Journal of Alloys & Compounds》 被引量: 10发表: 2008年 Study on Ultraviolet ...
In the architecture, a high quality master oscillator is configured to operate in a TE&, single frequency mode. The oscillator output is then directed into a slab power amplifier which is configured for 8 gain passes in a totally passively switched layout. After the fourth amplifier pass the ...
does not have enough energy to ionize atoms. However, it can cause molecules to vibrate and rotate, which means things will start heating up. Typically, the different types of non-ionizing radiation are classified by frequency, which is stated in units of “hertz”, abbreviated as “Hz”. ...
past a given point in a unit of time. Frequency is expressed in hertz (Hz). Wavelength and frequency are inversely proportional, and are related by λ=c/ν, where c is the speed of light. Thus, as the wavelength of the electromagnetic radiation increases, the corresponding frequency ...
fabrication process, relatively low dark current, ultrafast response speed and satisfactory high-frequency response performance [11], [12]. Traditional Schottky contacts require the deposition of metal electrodes with high work function, such as Au, Pt, and Pd [13], [14], [15]. However, the ...
