Journal ArticleDOI
Milliwatt-level frequency combs in the 8–14 μm range via difference frequency generation from an Er:fiber oscillator
Alessio Gambetta,Nicola Coluccelli,Marco Cassinerio,Davide Gatti,Paolo Laporta,Gianluca Galzerano,Marco Marangoni +6 more
TL;DR: This work reports on the generation of mid-infrared (mid-IR) pulses with a maximum average optical power of 4 mW and wide tunability in the 8-14 μm range via difference frequency generation (DFG) in GaSe from an Er:fiber laser oscillator.
Journal ArticleDOI
Diode-pumped passively mode-locked Yb:YLF laser.
TL;DR: In this article, the authors demonstrate passive mode-locking by means of a semiconductor saturable-absorber mirror in a diode-pumped Yb:YLF laser.
Journal ArticleDOI
Tm-doped LiLuF 4 crystal for efficient laser action in the wavelength range from 1.82 to 2.06 μm
Nicola Coluccelli,Gianluca Galzerano,Paolo Laporta,F. Cornacchia,Daniela Parisi,Mauro Tonelli +5 more
TL;DR: Room-temperature continuous-wave laser action in a novel Tm-doped LiLuF(4) crystal emitting at around 1.9 microm is demonstrated and an overall tunability extending from 1817 to 2056 nm, a slope efficiency of 46%, and a maximum output power in excess of 1.1 W are reported.
Journal ArticleDOI
Nonsequential modeling of laser diode stacks using Zemax: simulation, optimization, and experimental validation.
TL;DR: The validation of the model has been accomplished by comparing the simulated and experimental transverse irradiance profiles at different positions along the caustic formed by a lens.
Journal ArticleDOI
The optical frequency comb fibre spectrometer.
TL;DR: This work proposes a solution based on the combination of a frequency comb source and a fibre spectrometer, exploiting all-fibre technology, that is inherently low-cost, lightweight and may lead to the development of a new class of broadband high-resolution spectrometers.
