Application of Lasers for Sensing & Free Space Communication (LS&C)

Application of Lasers for Sensing & Free Space Communication (LS&C)

27 October - 01 November 2013
Marriott Paris Rive Gauche Hotel and Convention Center, Paris, France

The latest developments in laser based sensing and free space laser communication.

Sophisticated laser system concepts are increasingly being used to address high bandwidth free space optical (FSO) communications needs and for sensing applications.  We are coming into the age of Free Space Optics, where laser systems are seen as a viable competitor to RF systems for many applications. However, system requirements continue to demand increased performance from the various components used to implement these systems. Terrestrial and space based multi-mega/gigabit FSO links have been demonstrated but still require advances in beam steering, detection schemes,  adaptive optics and other methods of mitigating atmospheric effects, and modulated laser encoding before wide applications are to be realized. Optical sensors based on lasers are also progressing both in remote applications as well as in on chip sensing, in communities ranging from environmental sensing to medical diagnostics. Laser based sensing and free space communications both employ sophisticated detection schemes.  This meeting reports on the multiple applications of lasers in FSO communications as well as in advanced sensing applications.

SC290 High-power Fiber Lasers and Amplifiers

Johan Nilsson, Optoelectronics Research Ctr., Univ. of Southampton, UK

Course Level: Advanced Beginner (basic understanding of topic is necessary to follow course material)

Course Description: This course describes the principles and capabilities of high power fiber lasers and amplifiers, with output powers that can exceed a kilowatt. It describes the fundamentals of such devices and discusses current state of the art and research directions of this rapidly advancing field. Fiber technology, pump laser requirements and input coupling will be addressed. Rare-earth-doped fiber devices are the focus of the course, but Raman lasers and amplifiers will be considered, too, if time allows. This includes Yb-doped fibers at 1.0 - 1.1 μm, Er-doped fibers at 1.5 - 1.6 μm, and Tm-doped fibers at around 2 μm. Operating regimes extending from continuous-wave single-frequency to short pulses will be considered. Key equations will be introduced to find limits and identify critical parameters. For example, pump brightness is a critical parameter for some devices in some regimes but not always. Important limitations relate to nonlinear and thermal effects, as well as damage, energy storage and, of course, materials. Methods to mitigate limitations in different operating regimes will be discussed. Fiber, laser and amplifiers designs for different operating regimes will be described.

Intended Audience: This course is intended for scientists and engineers involved or interested in commercial and military high power fiber systems. This includes system designers, laser designers, fiber fabricators, and users. A basic knowledge of fibers and lasers is needed

Benefits and Learning Objectives
After completion of this short course the participant will be able to:

  • Describe the fundamentals of high power fiber lasers and amplifiers.
  • List key strengths, relative merits, and specific capabilities of high power fiber lasers and amplifiers.
  • Assess performance limitations and describe the underlying physical reasons in different operating regimes.
  • Design or specify basic fiber properties for specific operating regimes.
  • Describe the possibilities, limitations, and implications of current technology regarding core size and rare earth concentration of doped fibers.
  • Discuss different options for suppressing detrimental nonlinearities.
  • Design basic high power fiber lasers and amplifier systems.
  • List strengths and weaknesses of different pumping schemes.

SC406 Nonlinear Effects in Fibers

Thomas Schreiber, Fraunhofer IOF Jena, Germany

Course description:The extended nonlinear Schrödinger equation (NLSE) is the basic equation for the description of optical pulse propagation in fibers that experience various linear and nonlinear effects. The course will first focus on the basic effect and its understanding described by this equation like pulse broadening, spectral broadening (SPM, FWM, optical wave breaking), soliton effects, stimulated Raman scattering, supercontinuum generation, pulse amplification and pulse compression. Additionally, the fundamentals to numerically solve the equations are described. In a second part, the laser rate equations that can be applied to active fiber amplifier systems are discussed. Relevant effects that can be studied with the combination of the rate equation and nonlinear Schrödinger equation are introduces, for example, saturation of fiber amplifiers, broadband amplification, ASE background and noise and pump conditions. Furthermore, inelastic scattering processes of Brillouin and Raman scattering are considered. Finally, system designs, for instance short pulse fiber oscillators, are considered, where different fiber optical elements affect the output.

Intended Audience: This course would be useful to anyone working with fibers and is interested in understanding and predicting laboratory results.
 
Benefits and Learning Objectives
This course should enable you to:

  • describe  the basics of the nonlinear Schrödinger Equation and laser rate equations
  • compute and discuss the numerical solution to these equations, like the Split-Step Method
  • determine numerical stability issues
  • design fiber optics setups regarding nonlinear effects
