High-speed pulse train amplification in semiconductor optical amplifiers with optimized bias current [PDF]
In this paper, we have experimentally investigated the optimized bias current of semiconductor optical amplifiers (SOAs) to achieve high-speed input pulse train amplification with high gain and low distortion.

Room-Temperature Continuous-Wave Vertical-Cavity Single-Quantum-Well Microlaser Diodes [PDF]
Room-temperature continuous and pulsed lasing of vertical-cavity, single-quantum-well, surface-emitting microlasers is achieved at ~983nm. The active Ga[sub][0-8]In[sub][0-2]As single quantum well is 100 [angstroms] thick.

Inhomogeneous Gain Saturation in EDF: Experiment and Modeling [PDF]
Erbium-Doped Fiber Amplifiers can present holes in spectral gain in Wavelength Division Multiplexing operation. The origin of this inhomogeneous saturation behavior is still a subject of controversy.

Coherent beam combining with multilevel optical phase-locked loops [PDF]
Coherent beam combining (CBC) technology holds the promise of enabling laser systems with very high power and near-ideal beam quality. We propose and demonstrate a novel servo system composed of multilevel optical phase lock loops.

Transverse Bragg resonance laser amplifier [PDF]
We propose and analyze a new type of optical amplifier that is formed by addition of gain in the periodic cladding of a transverse Bragg resonance waveguide [Opt. Lett. 27, 936 (2002)]. Using the coupled-wave formalism, we calculate the mode profiles, the exponential gain constant, and, for comparison, the gain enhancement compared with those of ...

Wavelength Scaling of Laser Wakefield Acceleration for the EuPRAXIA Design Point
Scaling the particle beam luminosity from laser wakefield accelerators to meet the needs of the physics community requires a significant, thousand-fold increase in the average power of the driving lasers.

Suppression of stimulated Brillouin scattering in optical fibers using a linearly chirped diode laser [PDF]
The output of high power fiber amplifiers is typically limited by stimulated Brillouin scattering (SBS). An analysis of SBS with a chirped pump laser indicates that a chirp of 2.5 × 10^(15) Hz/s could raise, by an order of magnitude, the SBS threshold ...

2-kW Average Power CW Phase-Conjugate Solid-State Laser [PDF]
We have demonstrated stable operation of a 2-kW Yb:YAG phase-conjugate master oscillator power amplifier (PC-MOPA) laser system with a loop phase-conjugate mirror (LPCM). This is the first demonstration of a continuous wave (CW)-input LPCM MOPA operating
