Advances in optical frequency combs and their applications

Recent advances in the development of optical frequency combs based on both mode-locked lasers and micro-resonator devices will be reviewed. Precision frequency synthesis with these laser-based tools is enabling a range of applications in mid-infrared spectroscopy and trace gas sensing, optical clocks, waveform synthesis and astronomy.

High-power single-mode cw lasers for gravitational wave detection
The development of high-power solid-state lasers for gravitational wave detectors is presented, in particular with respect to the state-of-the-art lasers utilized in the current generation of these detectors. Furthermore, results on high-power fiber amplifiers regarding the next generation of gravitational wave detectors are presented and discussed.

High-power single-crystal fiber amplifiers
We present a study of the specificity of the pump guiding in the single crystal fiber (SCF) and give an overview of the results obtained using SCF gain modules in laser amplifiers including high power experiments and the last results obtained with picosecond multi-stages Yb:YAG SCF amplifiers.

Progress in optically-pumped semiconductor disc lasers
Recent progress in the development of gain and saturable absorber mirrors used in semiconductor disc lasers is reviewed. Emphasis is put on linking technological advances to laser performance, in particular concerning power scaling and wavelength coverage. An overview of emerging applications in spectroscopy and medicine is provided.

Peter Schunemann, BAE Systems, USA
Highly nonlinear crystals for ultrafast mid-IR frequency conversion
ZnGeP2 and CdSiP2, as well as the orientation-patterned semiconductors GaAs (OP-GaAs) and GaP (OP-GaP), exhibit the highest nonlinear optical coefficients among phase-matchable crystals with practical absorption losses and transparency ranges. Advances in growth and processing of these materials have extended ultrafast laser output deep into the mid-infrared.
Keywords—nonlinear optical crystals; mid-infrared; semiconductors; quasi-phasematching; ZnGeP2; ZGP; CdSiP2; CSP; OP-GaAs; OP-GaP.

G. K. Samanta, Physical Research Laboratory, India
Structured laser beams and novel applications
Structured laser beams are of great importance due to their wide range of scientific and technological applications. In this talk, we will discuss our recent results on generation of various structured laser beams including optical vortices, perfect vortices, Airy beam, and hollow Gaussian beam and some of their applications.

 

Fiber and Waveguide Devices

KEYNOTE SPEAKERS - INVITED SPEAKERS


Keynote Speaker: 

Ramachandran Siddharth Ramachandran, Boston University, ECE Department, Photonics Center, Boston, MA, USA
Intermodal nonlinear fiber optics: a new pathway to power scalable sources
Fibers stably guiding a multitude of Bessel-beam-like spatial modes help decouple the dispersion-versus-mode-area trade-off that often restricts achievable power levels via nonlinear-optical interactions in single-moded fibers and waveguides. We will discuss this design space and potential applications in fields as disparate as quantum-optics, nanoscale and deep-tissue imaging, and high-power lasers

Invited Speakers: 

Olivier Vanvincq, Université Lille 1, France
Active and passive solid-core microstructured fibers for laser applications
In this presentation, we will report our progress in solid-core photonic bandgap fibers for high power applications. We will focus on our strategies to achieve large mode area designs while keeping a single-mode behavior, based on 2D photonic bandgap fibers with hetero-structured cladding or pixelated Bragg fibers. In a second part, we will present our last realization of a microstructured single-mode fiber delivering a flat top intensity profile.

Thomas Gottschall, Friedrich-Schiller-Universität Jena, Germany
All-fiber optical parametric oscillator for bio-medical imaging
The first broadly tunable all-fiber optical parametric oscillator system is presented. This laser concept could very well be the missing key to establish non-linear imaging as a diagnostic tool in bio-medical domains.

Pu Zhou, National University of Defense Technology, China
Multi-kW-level near-diffraction-limited coherent polarization beam combining of fiber laser sources
Based on active phase control method, four channels of kilo-watt level narrow-linewidth linear-polarized fiber amplifiers are coherently polarization combined with a combining efficiency of 92%. The combined beam has an output power of 3.2 kW, and the beam quality M2 factor of the combined beam is ~1.3 @ 3kW.

Tso Yee Fan, MIT Lincoln Laboratory, USA
Beam combining of fiber amplifiers
Beam combining of arrays of lasers is becoming an increasing attractive approach to generate high-power and high-brightness sources. Coherent beam combining can scale the brightness by large amounts, in principle by as much as the number of elements.

Jean-Emmanuel Broquin, L'Institut de Microélectronique Electromagnétisme et Photonique et le Laboratoire d'Hyperfréquences et de Caractérisation (IMEP-LaHC), France
Rare-earth-doped active device on glass: from telecom to sensors
This paper reviews the activities carried-out on rare-earth-doped active devices made by ion exchange on glass at the IMEP-LaHC over the last decade. First the technology is presented, then results on Erbium lasers for airborne Lidar, Neodymium pulsed lasers for supercontinuum generation and recent developments on hybrid devices are shown.

It includes a THz based electron gun and accelerator with a nanostructured photocathode and optical undulator to from a Free-Electron Laser like coherent X-ray source. The source is driven by a 1J, 1kHz repetition rate picosecond Yb:YAG laser.

Energy partition and dynamics of absorption and ablation in burst-mode (>100 MHz) ultra-fast pulsed laser ablation in biotissues
100+ MHz burst-mode ultrafast-laser ablation of biological tissues depends on how each pulse interacts with the sample, thus ultimately on the state left over from the previous pulse. Measured dynamics of absorption show the impact of persistence of ionization, dissipation of plasma plume, and the driven oscillation of cavitation features.
