“Mixed khi(2) + khi(3) octave cavity solitons from multimode fibers”
Partnership: ICB (Uni Bourgogne Europe) + XLIM (Uni Limoges)
PI: Prof. Philippe Grelu — Co-PI: Dr. Vincent Couderc
Summary: The recent use of multimode fibers in ultrafast optics has unveiled a rising paradigm, where nonlinear processes, such as beam self-cleaning, can overcome the adverse effects of the intermodal dispersion. This inspires the development of the next generation of ultrashort fiber lasers, which should have a larger versatility in terms of pulse profile, spectral coverage, and energy scalability, thus meeting an extended range of applications. However, the field of multimode nonlinear optics is still in its infancy, with its potential to extend the spectral coverage of coherent sources clearly underused. In the OSMOSIS project, we shall demonstrate a new laser source able to self-generate both fundamental and harmonic waves in the ultrashort-pulse regime. To achieve this, we will use optical poling to write an innovative second-harmonic generation (SHG) function directly within a multimode optical fiber. This special SHG fiber will be inserted in a versatile fiber laser cavity featuring extensive control over temporal, spectral and spatial degrees of freedom, to select phase matched nonlinear processes along with spatiotemporal mode-locking. The major asset of the OSMOSIS project is the complementarity between ICB and XLIM partners, at the state-of-the-art concerning nonlinear processes in multimode fibers (XLIM) and ultrafast laser dynamics and characterization (ICB). Fulfilling this ambitious objective will have far reaching impacts. In fundamental physics, we shall demonstrate the existence of a novel solitary wave: a (FF + SH) soliton arising from both second order and third order nonlinearities, which we call an octave soliton, and represents a spectral and spatiotemporal generalization of dissipative solitons. Concerning potential applications, our novel source will pave the way for a robust self-referenced frequency comb sources spanning over an octave, which will also benefit from the power scaling potential of multimode fibers.
Preliminary results:
There is currently a great incentive to develop ultrafast fiber lasers using multimode fibers (MMF). Since MMF offer larger mode areas (LMA) than SMF, they represent an interesting solid-core alternative to the delicate use of microstructured LMA fibers in fiber lasers for pulse energy scaling. However, ultrafast fiber lasers with MMFs are prone to important spatiotemporal instabilities, and their energy scaling benefit has not been clearly established so far. For the first time, we combined the energy-managed soliton laser approach with the use of multimode fibers, here with a commercially available few-mode step-index gain fiber.

- Original hybrid multimode-singlemode energy-managed soliton fiber laser
- Record breaking pulse energy generation compared to multimode ultrafast fiber lasers operated in the anomalous dispersion regime
- Remarkable laser output flexibility in terms of pulse duration and repetition rate
- High 22% pump to ML laser output energy efficiency in the 1.5-micron region.
- Spatiotemporal laser dynamics experimentally characterized
- Self-starting, stable mode-locked operation demonstrated, spatiotemporal instabilities being mitigated by strong dissipation
The energy-managed mode-locked laser architecture allows to scale the pulse energy with the pulse duration, contrarily to the energy scaling originating from conventional (NLS) solitons. For pulse duration larger than 5 ps, the chromatic dispersion effect arising from the optical fibers becomes negligible, leading to an efficient and flexible dispersion-less dissipative soliton mode locked laser regime. We demonstrate microjoule pulse energy level for long picosecond pulses out of standard off-the-shelf fiber optical components. Further energy scaling is achieved within a hybrid fiber laser incorporating a few-mode gain fiber.

“Towards multifunctional two-micron ultrafast fiber lasers for high-precision biomedical applications”
Partnership: ICB (Uni Bourgogne Europe) + IITH (Indian Institute of Technology of Hyderabad)
French PI: Prof. Philippe Grelu — Indian PI: Prof. Nithyanandan Kanagaraj
Summary: Lasers have transformed the biomedical domain with their remarkable diagnostic and therapeutic abilities. Yet, most modern-day laser-based applications are based on a ‘one-size fits all’ approach, often leading to sub-optimal performance. Using the ‘off-the-shelf’ lasers for a therapeutic procedure provides limited or no flexibility to medical practitioners on the laser parameters. This has become a challenge in high-precision therapeutic applications such as laser surgery, where there is a strong desire for optimized laser solutions to avoid excessive thermal damage. By using innovative laser cavity design and optimized by artificial intelligence, we intend to provide a flexible two-micron fiber laser solution, that can deliver an optimized laser output, in terms of wavelength, repetition rate, pulse energy, etc., allowing surgeons to choose “on the fly” the proper laser parameters. With laser being the central unit in various medical devices, a flexible two-micron laser source could be a one-stop solution for various biomedical applications, paving the way to a “Best and Affordable healthcare.”
Preliminary results:
Development of energy-efficient & flexible 2-micron lasers
- Realized the first 2-μm ‘energy-managed soliton laser’ using only anomalous dispersion standard silica fibers, producing up to 12-nJ sub-picosecond pulses. This breakthrough enables cost-effective, compact ultrafast lasers using readily available components. Further, the laser’s wavelength tunability from 1850 to 1960 nm and the generation of soliton molecules provide access to rich nonlinear dynamics. Such lasers have strong applicative prospects for minimally invasive surgeries, mid-infrared phototherapy, and nonlinear imaging due to their high peak powers and short pulse durations in the biologically transparent 2-μm window

- Designed and numerically validated a broadband Tm-doped fiber amplifier (TDFA) using a novel ‘gain-guiding’ mechanism, demonstrating ultra-flat gain (±0.05 dB variation) over a 296-nm range. This amplifier design ensures uniform performance across a wide spectral range, enabling simultaneous amplification of multiple wavelengths. It has potential applications in advanced medical diagnostics (e.g., multispectral imaging), environmental sensing, and secure communications, especially in the emerging 2-μm telecom band.

- Realized a high-energy, narrowband (~0.3 nm), picosecond (~15 ps) soliton laser demonstrated through the combination of energy-management scheme with a pulse-compression effect influenced by chirped fiber Bragg grating. This narrowband, compact all-fiber laser should be beneficial for high-precision laser-assisted surgical procedures.
