“…The engineering of a handheld microscope or endoscope is itself a broad subject, with a new trend toward the maximization of fiber‐based components, or equivalently, the minimization of free‐space components . This development trend of the application‐dependent light‐delivery module parallels the similar development trends of the ultrafast fiber source laser and the (optional) intermediate optics in this review (Sects. 2–5), reflecting the ultimate goal of a fiber‐format system and instrumentation immune to mechanical and thermal perturbations.…”

“…However, ultrafast fiber source lasers with comparable pulse properties are favored in (portable) biophotonics applications because of their compactness, robustness, single spatial mode, thermal stability, chemical inertness, power scalability, and (potentially) low cost. Comprehensive overviews have been provided on high‐power fiber oscillators and fiber master‐oscillator‐power‐amplifiers (MOPA) . Both configurations have been influenced by the PCF technology and fiber supercontinuum generation .…”

Biophotonics and nonlinear fiber optics have traditionally been two independent fields. Since the discovery of fiber-based supercontinuum generation in 1999, biophotonics applications employing incoherent light have experienced a large impact from nonlinear fiber optics, primarily because of the access to a wide range of wavelengths and a uniform spatial profile afforded by fiber supercontinuum. However, biophotonics applications employing coherent light have not benefited from the most well-known techniques of supercontinuum generation for reasons such as poor coherence (or high noise), insufficient controllability, and inadequate portability. Fortunately, a few key techniques involving nonlinear fiber optics and femtosecond laser development have emerged to overcome these critical limitations. Despite their relative independence, these techniques are the focus of this review, because they can be integrated into a low-cost portable biophotonics source platform. This platform can be shared across many different areas of research in biophotonics, enabling new applications such as point-of-care coherent optical biomedical imaging.

Optical frequency combs have revolutionized optical frequency metrology and are being actively investigated in a number of applications outside of pure optical frequency metrology. For reasons of cost, robustness, performance, and flexibility, the erbium fiber laser frequency comb has emerged as the most commonly used frequency comb system and many different designs of erbium fiber frequency combs have been demonstrated. We review the different approaches taken in the design of erbium fiber frequency combs, including the major building blocks of the underlying mode-locked laser, amplifier, supercontinuum generation and actuators for stabilization of the frequency comb.

“…Nonlinear-optical PCF components have been shown to be ideally suited to work in combination with Ti:Sapphire and Cr:Forsterite solid-state mode-locked sources [3][4][5]15], as well as with ytterbium fiber lasers [16][17][18][19].…”

Widely tunable 70-MHz near-infrared source of ultrashort pulses based on a mode-locked ytterbium laser and a photonic-crystal fiber

et al. 2010

Soliton self-frequency shift in a highly nonlinear photonic-crystal fiber is shown to enable an efficient wavelength conversion of 100-fs 70-MHz output of a solid-state ytterbium laser, allowing the generation of sub-100-fs laser pulses with a central wavelength tunable from 1060 to 1400 nm. In the single-soliton regime, laser pulses are efficiently converted into isolated wavelength-tunable bands, with a photon-number conversion efficiency of 82% achieved for ytterbium-laser pulses converted to a spectral band at 1125 nm supporting 35-fs transform-limited pulses. For high input powers, the ytterbium-laser pulses are coupled to multiple solitons inside the fiber, enabling efficient supercontinuum generation through involved soliton dynamics.
