Book excerpt: The overall goal of the Phase I Supplement was to improve the performance of the bench-top, mid-infrared fiber laser system that had been developed under the Phase I program. The program succeeded in demonstrating an all-fiber integrated Mid-InfraRed Fiber Laser (MIRFIL), see Figure 1, with no optical bench, such that bulk optics are no longer required. More specifically, the all-fiber integrated MIRFIL breadboard generates super-continuum (SC) with 1.2W time-averaged power extending to -3.4 microns in 60m of ZBLAN fiber. The long wavelength edge of the SC is limited by the bend-induced loss of the particular ZBLAN fiber used in the experiments. The power levels and repetition have been optimized to generate high time-averaged power along with the broadest spectrum supported by the fiber. In addition, the results from the all-fiber integrated MIRFIL are compared with results obtained using the same ZBLAN fiber in a bulk-optical, tabletop, set-up in Prof. Almantas Galvaunaskas's lab, and the results lay almost directly on top of each other. In order to broaden the spectrum out to -4.6 microns, new ZBLAN fibers with less bend-induced loss will be required, and we are working with fiber makers to fabricate this fiber while maintaining a high damage threshold. One of the first tasks was to implement and characterize the first stage pre-amplifier. The pulse repetition rate in the pre-amplifier can be varied from 20kHz to 500kHz, and the power is scaled up by increasing the repetition rate.

Download or read book Mode locked Thulium doped Fiber Lasers for Supercontinuum Generation in the Mid infrared written by Charles William Rudy and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there has been significant interest in the "eye-safer" 2-[micrometer] wavelength range for applications varying from laser-driven particle acceleration to remote sensing to mid-infrared spectroscopy. Trivalent thulium has shown promise as a viable dopant to fulfill several requirements of these applications through its wide gain bandwidth, from ~1.8 to 2.1 [micrometers], and its ability to efficiently power scale. By further broadening the output spectrum of an ultrafast Tm-doped fiber source through supercontinuum generation (SCG), an instantaneously broadband mid-IR spectrum can be produced, which is particularly useful for mid-IR spectroscopy. In this dissertation, I demonstrate thulium's ability to generate ultrafast pulses in a mode-locked all-fiber laser, the figure-eight laser (F8L). Through the various operating regimes of the F8L, pulse widths ranging from 1.5 ps to 20 ns could be generated. Amplification of the F8L output allowed for temporal pulse compression to less than 400 fs with ~100 kW of peak power. In addition to the F8L, a subharmonic optical parametric oscillator (OPO) was explored as a possible 2-[micrometer] oscillator. The sync-pumped doubly-resonant OPO converted pulses from a 1-[micrometer] mode-locked fiber laser to 2 [micrometers], utilizing a PPLN crystal as the nonlinear gain medium. The subharmonic OPO generated less than 50-fs pulses, shorter than any reported Tm-doped oscillator to date. To utilize these sources for mid-IR spectroscopy, the spectral bandwidth can be significantly broadened through SCG. With a tapered chalcogenide fiber pumped by a Tm-doped fiber laser, the output spectrum was broadened from ~227 nm centered at 2.04 [micrometers] to span from 1 to 3.7 [micrometers].

Download or read book Pulsed Fiber Lasers with Multimode Interference Saturable Absorber written by Arslan Anjum and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Modelocked mid-infrared (mid-IR) lasers are an essential tool for applications like spectroscopy, metrology and laser surgery. They provide narrow pulse width and high peak power, which also makes them an ideal source for parametric oscillators and supercontinuum generation. Development of fiber based mid-IR ultrafast lasers is limited by the availability of fiber components like optical isolators, couplers and saturable absorbers that are compatible with operation in the wavelength window of 2-12 um. This thesis investigates the design of a fiber based saturable absorber that is suitable for modelocking mid-IR fiber lasers. The saturable absorber is based on nonlinear multimode interference in a multimode fiber and it operates in reflection mode. The all-fiber design of the saturable absorber eliminates the need for free-space alignment. Furthermore, the reflection mode operation makes it suitable for linear cavity laser design, which removes the need for optical isolators and additional fiber couplers. First, the proposed saturable absorber is constructed with a silica based graded index multimode fiber. This saturable absorber leads to generation of modelocked noise-like pulses in a thulium doped fiber laser. Afterwards, a mid-IR compatible version of the saturable absorber is built using an As-S-Se based step index multimode fiber. Using this device, stable mode-locked operation and resembling pulse operation are demonstrated at a wavelength of 1.9 um"--

Download or read book A New Generation of Ultrafast Oscillators for Mid Infrared Applications written by Nathalie Nagl and published by Springer Nature. This book was released on 2022-02-01 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the first successful realization of a compact, low-noise, and few-cycle light source in the mid-infrared wavelength region. By developing the technology of pumping femtosecond chromium-doped II-VI laser oscillators directly with the emission of broad-stripe single-emitter laser diodes, coherent light was generated with exceptionally low amplitude noise — crucial for numerous applications including spectroscopy at high sensitivities. Other key parameters of the oscillator's output, such as pulse duration and output power, matched and even surpassed previous state-of-the-art systems. As a demonstration of its unique capabilities, the oscillator's powerful output was used to drive — without further amplification — the nonlinear generation of coherent mid-infrared light spanning multiple octaves. The resulting table-top system uniquely combines high brilliance and ultrabroad spectral bandwidth in the important mid-infrared spectral range. The rapid development of this technology is comprehensively and lucidly documented in this PhD thesis. Together with a thorough review of literature and applications, and an extensive analysis of the theoretical foundations behind ultrafast laser oscillators, the thesis will serve as a valuable reference for the construction of a new generation of mid-infrared light sources.
