We present results on high-average power difference frequency generation of pulsed Yb/Er fiber systems to the mid-IR (6.2 W at 3.35 μm), and use focused Gaussian beam theory to validate our experimental results. OCIS codes: (190.4970) Parametric oscillators and amplifiers; (140.3070) Infrared and far-infrared lasers; (140.3510) Lasers, fiber

New moderate-resolution mid-infrared spectroscopy at 10 μm of 27 infrared galaxies is presented. The galaxies have been chosen from three 60 μm selected and one 12 μm selected complete flux-limited catalogs of galaxies; 17 of these sources have LIR(8– 1000μm) ≥ 5 × 10 L⊙. A high-resolution spectrum of the source Arp 299B1 is also presented. Combining these new results with previously published ...

We use Planck data to detect the cross-correlation between the thermal Sunyaev-Zeldovich (tSZ) effect and the infrared emission from the galaxies that make up the the cosmic infrared background (CIB). We first perform a stacking analysis towards Planck-confirmed galaxy clusters. We detect infrared emission produced by dusty galaxies inside these clusters and demonstrate that the infrared emissi...

We present a green and scalable route toward the formation of reduced graphene oxide (r-GO) by photothermal reduction induced by infrared (IR) irradiation, utilizing a bathroom IR lamp as the source of IR light. Thermogravimetric analysis, Raman, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy confirm the reduction of r-GO by IR light. Ultraviolet-visible-infrared s...

The angular power spectra of the infrared maps obtained by the DIRBE (Diffuse InfraRed Background Experiment) instrument on the COBE1 satellite have been obtained by two methods: the Hauser-Peebles method previously applied to the DMR maps, and by Fourier transforming portions of the all-sky maps projected onto a plane. The two methods give consistent results, and the power spectrum of the high...

A facility to generate high-intensity, ultra-short pulses of broad-band far-infrared radiation has been assembled and tested at Stanford.’ The device uses sub-picosecond relativistic electron bunches to generate coherent radiation through transition or synchrotron radiation in the far-infrared (FIR) regime between millimeter waves and wavelengths of about 100pm and less. Experimental results sh...

Infrared power corrections for the average thrust T in e + e − annihilation are analyzed in the framework of renormalon resummation, motivated by analogy with the skeleton expansion in QED and the BLM approach. Performing the " massive gluon " renormalon integral a renormalization scheme invariant result is obtained. We find that a major part of the discrepancy between the known next-to-leading...

Infrared thermal microscopy is a widely used tool for the thermal analysis of microelectronic circuits [1]. It is a noncontact measurement technique and utilizes naturally emitted infrared radiation from a sample. Commercial IR microscopes are readily available, offering a maximum spatial resolution of ~ 3 μm and a range of analysis options, including real time thermal mapping and thermal trans...

A bolometer detector system was developed for the high accuracy infrared spectrophotometer at the National Institute of Standards and Technology to provide maximum sensitivity, spatial uniformity, and linearity of response covering the entire infrared spectral range. The spatial response variation was measured to be within 0.1 %. The linearity of the detector output was measured over three deca...

Near-infrared up-conversion lasing in erbium(Er)-yttrium(Y) chloride silicate nanowires was demonstrated when pumped by 1476 nm laser at room temperature. The emission covers a very wide wavelength range (400-1000 nm). A clear threshold for 985 nm peak was observed at a launched average pump power of approximately 7 mW. Above threshold, the intensity increases linearly when turning up the pump ...
