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 ...
Intense laser field effect on the nonlinear optical properties of triple quantum wells consisting of parabolic and inverse-parabolic quantum wells
(Laser Physics, 25/02/2022)
The nonlinear optical rectification, the second harmonic generation coefficient, and the third harmonic generation coefficient in parabolic-inverse parabolic-parabolic quantum wells (PIPPQWs) and inverse parabolic-parabo ...
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 ...
Linear and nonlinear optical properties of semi-elliptical InAs quantum dots: Effects of wetting layer thickness and electric field
(Thin Solid Films, 2022/8/1)
In this paper, we have studied the optical properties of semi-elliptical InAs quantum dots (QDs) embedded in GaAs. Under effective mass approximation, the finite element method has been used to obtain wavefunctions and ...
