The saturation spectrum of the D_2-line of 85Rb and 87Rb was recorded with a resolution close to the natural line width. Distributed Feedback (DFB) and Distributed Bragg Reflector (DBR) laser diodes are the light sources emitting extremely narrow spectral line with bandwidth below 5MHz and typical Side Mode Suppression Ratio (SMSR) > 40dB. Sacher Lasertechnik celebrates 20th anniversary A view on exciting and moving years of a small but smart company in laser technology. More details for QFLD-780-100S can be seen below. In this article we present a detailed test of a DFB laser for spectroscopy of the rubidium D 2-line and the two-photon 5S-5D transition. • 1310nm DFB. expect 40% conversion => 5. 1–6 (2004) / DOI 10. By optimizing the cavity length and grating coupling coefficient, the wavelength was 780 nm and the line width was 35 kHz for a 279 mW laser output [13,14]. We can used cheap and robust telecoms components such as : phase modulators, optical isolator, very robust and controllable DFB laser diode (telecoms standards). Absorption and Raman spectroscopy, environmental analysis, process control, biomedical. With the advantages of high resolution, a strong anti-active jamming ability, small volume, light weight, and low cost, new solid-state lidars can meet the requirements of intelligent cars in the future. Additional areas of development include DFB lasers operating at 780 nm for chip-scale atomic systems. 780 nm) are visible and are very damaging. Sep 15, 2012 · Abstract. 5 m, while the right panel of Fig. Glaucoma is a serious eye disease that often leads to blindness. Infrared lasers, CrystaLaser manufactures compact infrared laser including CW Infrared laser and Q-switched Infrared laser, single longitudinal mode infrared laser, compact high power DPSS infrared lasers made in the US. SINGLE FREQUENCY LASER DIODES Distributed Feedback Laser 780 nm DFB Laser with hermetic Butterfly Housing PM Fiber with angle-polished Connector Model : EYP-DFB-0780-00040-1500-BFY02-0x0x Wavelength : 780nm Output Power : 10mW. Orlando September 2002. Shop pin diode now!

Synchronization jitter with respect to RF reference. We provide infrared laser diodes in variety of packages. Wavelength (nm) Typical Power (mW) Spectral Width (nm) Laser Type Minimum Typical Maximum 395 405 415 20 1 FP 440 445 450 10 1 FP 630 633 635 10 1 FP 632 635 638 1 0. Boreal Laser’s GasFinder stationary product line can be used for the immediate and unambiguous detection of leaks/releases of combustible, toxic, or hazardous gas(es) that result in the early warning or executive action for the protection of operational personnel and assets. GaAs Semiconductor Laser Diode. 2015 Distributed Feedback Laser RWE/RWL BAL DFB/DBR TPL/TPA General Product Information Product Application. Front Facet Reflectivity of 780 nm DFB Diode Lasers at High Optical Output Power. Applications incl. In the world of diode lasers, there are currently four main configurations to obtain a single-frequency output: external cavity laser (ECL), distributed feedback (DFB), volume holographic grating (VHG), and distributed Bragg reflector (DBR). 24 nm GaAs/AlGaAs distributed feedback (DFB) lasers aimed at 87Rb cold atom systems operating at 20 ˚C with over 50 mW of power and side-mode suppression ratios of 46 dB using sidewall gratings and no regrowth. 波長735~1550nm(FBG付、DFBレーザもあり) スーパールミネッセントダイオード(SLD) 波長780~1560nm(ファイバ付、9mm canなど) ファイバ付LEDモジュール 波長1300nm、1550nm SOAモジュール 波長980nm、1050nm、1310nm、1550nm. Single Frequency Laser Diodes. Learn about DFB Interband Cascade Lasers. Not Available adshelp[at]cfa. The K-DFB lasers feature an excellent spectral stability with a short term (10 µs) FWHM linewidth of 320 kHz, and their intrinsic linewidth corresponds to 5 kHz. eagleyard Photonics is a leading provider of high-power laser diodes with wavelengths ranging from 630 nm to 1,120 nm. Infrared lasers, CrystaLaser manufactures compact infrared laser including CW Infrared laser and Q-switched Infrared laser, single longitudinal mode infrared laser, compact high power DPSS infrared lasers made in the US. In laser 3 a DFB-diode with a specified linewidth of less than 2 MHz and a center wavelength of k c = 780 nm is implemented. After amplification in an Erbium-doped fiber amplifier chain (EDFA), the light is frequency doubled in periodically poled Lithium Niobate. Nguyen 1, H. By optimizing the cavity length and grating coupling coefficient, the wavelength was 780 nm and the line width was 35 kHz for a 279 mW laser output [13,14].
