43 μm fiber laser in CO2-filled hollow-core silica fibers
Rare-earth-doped fiber lasers at 3–5 μm can provide a variety of applications in defense, security, medicine, and so on. Limited by the maximum phonon energy of silicate glass host at room temperature, these lasers are normally based on soft-glass ...

Generation of Arbitrary Frequency Chirps with a Fiber-Based Phase Modulator and Self-Injection-Locked Diode Laser [PDF]
We present a novel technique for producing pulses of laser light whose frequency is arbitrarily chirped. The output from a diode laser is sent through a fiber-optical delay line containing a fiber-based electro-optical phase modulator. Upon emerging from

Ultra-broadband wavelength-swept Tm-doped fiber laser using wavelength-combined gain stages [PDF]
A wavelength-swept thulium-doped fiber laser system employing two parallel cavities with two different fiber gain stages is reported. The fiber gain stages were tailored to provide emission in complementary bands with external wavelength-dependent ...
