TL;DR: In this paper, a review of diode laser-based spectroscopy is presented, which covers the developments made so far and illustrates the properties of free-running diode lasers.
Abstract: Spectroscopy using tunable diode lasers is an area of research that has gone through a dramatic evolution over the last few years, principally because of new exciting approaches in the field of atomic and molecular spectroscopy. This article attempts to review major recent advancements in the field of diode laser based spectroscopy. The discussion covers the developments made so far in the field of diode lasers and illustrates comprehensively the properties of free-running diode lasers. Since the commercially available free-running diode lasers are not suitable for high-precision spectroscopic studies, various techniques developed so far for converting these free-running diode lasers into true narrow linewidth tunable laser sources are discussed comprehensively herein. The potential uses of diode lasers in different spectroscopic fields and their extensive list of applications have also been included, which may be interesting for the novice and the advanced user as well.

TL;DR: In this paper, the soliton operation and wavelength tuning of erbium-doped fiber laser with atomic layer graphene was investigated under various cavity dispersion conditions, and it was shown that not only wide range soliton wavelength tuning but also soliton pulse width variation could be obtained in the fiber laser.
Abstract: Soliton operation and soliton wavelength tuning of erbium-doped fiber lasers mode locked with atomic layer graphene was experimentally investigated under various cavity dispersion conditions. It was shown that not only wide range soliton wavelength tuning but also soliton pulse width variation could be obtained in the fiber lasers. Our results show that the graphene mode locked erbium-doped fiber lasers provide a compact, user friendly and low cost wavelength tunable ultrashort pulse source.

TL;DR: In this paper, the authors describe the experimental setup, pulse sequence, heterodyne de-tection, and extraction of the mainly absorptive part of the 2D-IR spectrum.
Abstract: Ultrafast two dimensional infrared (2D-IR) vibra- tional echo spectroscopy has emerged as a powerful method for the study of molecular dynamics under thermal equilibrium con- ditions occurring on ultrafast time scales. Here, we describe ex- perimental details of 2D-IR vibrational echo spectroscopy in- cluding the experimental setup, pulse sequence, heterodyne de- tection, and extraction of the mainly absorptive part of the 2D- IR spectrum. As an experimental example, the measurements of the hydrogen bond dynamics of neat water and water in a high concentration of NaBr solution are presented and compared. The experiments are performed on OD stretching vibration of dilute HOD in H2O to eliminate contributions from vibrational exci- tation transport. A new experimental observable for extracting dynamical information that yields the frequency-frequency cor- relation function is presented. The observable is the inverse of the center line slope (CLS) of the 2D spectrum, which varies from a maximum of 1 to 0 as spectral diffusion proceeds. The CLS is the inverse of the slope of the line that connects the maxima of the peaks of a series of cuts through the 2D spectrum that are parallel to the frequency axis associated with the first radiation field-matter interaction. Comparisons of the dynamics obtained from the data on water and the concentrated NaBr solutions show that the hydrogen bond dynamics of water around ions are much slower than in bulk water.

TL;DR: In this article, a Cr:forsterite master oscillator at 1250 nm, a stretcher, three optical parametrical amplifiers based on KD*P crystals providing 38 J energy in the chirped pulse at 910 nm central wavelength, and a vacuum compressor providing 43 fs pulse duration.
Abstract: 560 TW peak power has been achieved experimentally using a Cr:forsterite master oscillator at 1250 nm, a stretcher, three optical parametrical amplifiers based on KD*P crystals providing 38 J energy in the chirped pulse at 910 nm central wavelength, and a vacuum compressor providing 43 fs pulse duration. To our knowledge, it is a world-record OPCPA system and one of the five most powerful laser systems currently available.
