SC290 High Power Fiber Lasers and Amplifiers
12:30 - 15:30 - Sunday, 16 November
Johan Nilsson; Univ. of Southampton, UK
: Advanced Beginner (basic understanding of topic is necessary to follow course material)
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.
Benefits and Learning Objectives:
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.

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.
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.

SC422 Current Trends in Ultrashort Pulse Laser Technology
12:30 - 15:30 - Sunday, 16 November
Andrius Baltuska, Technische Universität Wien, Austria
The first part of the four-part lecture will highlight the rapidly growing scope of industrial, scientific, medical and sensing applications of femtosecond laser pulses and underscore unique light—matter interaction regimes enabling “cold” ablation, multiphoton bulk processing, femtosecond filamentation, tunable and broadband optical frequency conversion, coherent short-pulse X-ray and THz emission, etc., which only femtosecond lasers and no other laser technology can currently provide. Using three specific case studies, we will first summarize the shifting parameter space imposed on femtosecond sources by fledgling high-volume industrial and biomedical applications before examining the types of laser technology behind such sources. In the second part, we will identify, with brief descriptions, the main generic building blocks, such as oscillators, amplifiers, delivery systems, and survey main concepts, such as mechanisms of broadband modelocking, chirped-pulse laser and parametric amplification and alternatives to temporal pulse chirping, external compression, optical synchronization, coherent pulse combining and beam combining. In the third part, we will take a look at specific modern ultrafast optically pumped solid-state crystal oscillators and amplifiers and fiber lasers that are already playing a key role in the industrial and scientific market or are likely to occupy an important niche in the foreseeable future. We will examine the trends in the scaling of average power and peak power, repetition rate, laser wavelength, and pulse bandwidth. In particular, alternative technological routes such as laser amplification, parametric amplification and amplifier-free multiplexing/coherent addition will be juxtaposed to help the audience appreciate the strengths, weaknesses and symbiotic relations among the major competing concepts. In the final part, aimed at the course participants interested in extreme ultrafast optics, we will review several schemes that have succeeded in generating scalable near-single-cycle high-energy “ultimate” laser pulses and light transients measuring shorter than an optical cycle and discuss their applications.
Benefits and Learning Objectives:
Identify the key principles for the generation and amplification of femtosecond laser pulses.
Compare the main types of ultrafast optical amplifiers.
Determine which major subsystems are required in a femtosecond laser scheme dependent on the output target energy, duration, and average power.
Explain the main qualitative differences between broadband femtosecond laser chains and narrowband pulsed lasers.
Compare the engineering effort, material limits and system scalability for the key types of femtosecond systems.
The target audience are graduate students and engineers working in laser optics and technology; industrial and academic attendees who are users or developers of laser-based processing of materials and tissues; medical and biological researchers using lasers in diagnostics, microsurgery and dentistry; researchers active in ultrafast spectroscopy and strong field applications; environmental scientists employing laser-driven spectrometric and/or nonlinear-optical spectroscopic techniques; defense experts with the background in optical countermeasures.
