324-fs Pulses From a SESAM Modelocked Backside-Cooled 2-μm VECSEL
(IEEE Photonics Technology Letters, 2022/3/2)
We present the first modelocked backside-cooled GaSb VECSEL (Vertical External Cavity Surface Emitting Laser) operating above 2 μm . Using a two quantum well InGaSb SESAM (SEmiconductor Saturable Absorber Mirror) in a ...
Bandgap engineering, monolithic growth, and operation parameters of GaSb-based SESAMs in the 2–2.4 μm range
(Optical Materials Express, 2022/6/1)
We present the detailed growth and characterization of novel GaSb-based semiconductor saturable absorber mirrors (SESAMs) operating in the 2–2.4 µm spectral range. These SESAMs at different wavelengths are bandgap engineered ...
High-power low-noise 2-GHz femtosecond laser oscillator at 2.4 μm
(Optics Express, 2022/2/14)
Femtosecond lasers with high repetition rates are attractive for spectroscopic applications with high sampling rates, high power per comb line, and resolvable lines. However, at
long wavelengths beyond 2 µm, current laser ...
