We have dyes in stock at the HSLF to cover the wavelength range from 520-1000 nm. 2m) in air clean booth Optical Frequency Comb Profilometry Femtosecond laser (Femtolasers, RAINBOW). The operating wavelength was centered at 800 nm. Newport ニューポート社の除振台、モーションコントロール製品(ステージ、Picomotorアクチュエータ等)、波長可変レーザー、光学部品(オプティクス、光学マウント類等)、光計測器は、株式会社日本レーザーでお取り扱いしています。. The Spectra-Physics ® Solstice ® Ace ™ was the first femtosecond ultrafast amplifier designed, built and tested to meet rigorous industrial standards. suite 1002 toronto, ontario, m4v1l5 (416) 962-9600 fax (416) 962-9601 82 1 spectra physics portable desiccant dryer 83 1 spectra physics 409-08 picosecond autocorrelator 84 1 12 station filter holder assembly with controller board 85 1 12 station filter holder assembly with controller board. Time correlation functions were analyzed with a Laplace inversion program (CONTIN). An autocorrelator is a versatile, easy-to-use diagnostic tool for measuring the pulse shape and duration of ultrafast laser pulses. Studyres contains millions of educational documents, questions and answers, notes about the course, tutoring questions, cards and course recommendations that will help you learn and learn. It has a worldwide membership of around 50 000 comprising physicists from all sectors, as well as those with an interest in physics. Spectra Physics Inc 7300-L3 7300 Laser Diode. Kapteyn Department of Physics, Washington State University, Pullman, Washington 99164-2814 Received May 5, 1995 We have developed a Ti:sapphire amplifier system capable of producing pulses of 1 mJ, with 20-22. 7 deconvolution factor) is used to determine pulse width (FWHM) from autocorrelation signal as measured with Newport PulseScout® autocorrelator. The repetition rate of the pulses was 1 kHz. using an autocorrelator (model 409-08, Spectra Physics), which employs second harmonic generation with background free configuration technique. The purpose of this work is to characterize the optical spectra of an ultrafast optical parametric laser amplifier and measure the temporal pulse width o f the ultrafast laser system. ‡ Korea Institute of Science and Technology. 5 W of the multiline visible output from an argon ion laser (Spectra Physics 2040E) to produce an 82 MHz train of low energy (˘13 nJ, 1. The operating wavelength was centered at 800 nm. The laser pulse shape was optimized using a double prism com-pressor and monitored with the aid of an autocorrelator. * Current APS drive laser Configuration, and features Problems and solutions Current performances, and surprises Summary Slideshow. Sappire レーザー(“MaiTai”,Spectra Physics 社 製)を用いた。中心周波数808 nm(780~850 nm で 可変),スペクトル半値幅11 nm,時間半値幅~100 fs,繰り返し周波数79. Excitation and emission spectra of mucosal tissue and tissue components are correlated to spectra of endogenous chromophores. Wachtveitl a and M. A subsequent variable attenuator controls the delivered laser power. The minimum duration of pulses was 54 fs and could vary due to their chirping in a. The dynamic range reaches 11 orders of magnitude and thus is sufficient for the most demanding applications. (builded by Spectra Physics) consists of an oscil-lator (Maitai, 28 fs and 80 MHz) and stretcher, followed by a regenerative amplifier (Spitfire), which works at 1 kHz repetition rate. Both the output and input coupler mirrors were wedged at 2¡ to avoid etalon e⁄ects that might cause undesir-. Included are fiber-based systems capable of pulse widths in the tens of femtoseconds with wavelengths in the visible and IR. com Issue: September 2008. Moreover, the number of active modes is also finite, depending on the bandwidth of the net gain Δν. As part of our HarmoniXX product line, the HarmoniXX FHG - Fourth Harmonic Generation - is a frequency converter for quadrupling the frequency of ultra short-pulse lasers. (Spectra Physics Spitfire), a two-pass Ti:sapphire amplifier pumped by a Quanta-Ray Nd:YAG laser and a compressor. using an autocorrelator (model 409-08, Spectra Physics), which employs second harmonic generation with background free configuration technique. Photoionization and photofragmentation of gaseous toluene using 80-fs, 800-nm laser pulses A. All solutions were prepared from the stock solution. These are just a few of the high end manufacturers we carry. Digital Source Meter (1대) 8.
