Characterization of a High-Speed, High-Power Semiconductor Master-Oscillator Power-Amplifier (MOPA) Laser as a Free-Space Transmitter
Semiconductor lasers offer promise as high-speed transmitters for free-space optical communication systems. This article examines the performance of a semiconductor laser system in a master-oscillator power-amplifier (MOPA) geometry developed through a Small Business Innovation Research (SBIR) contract with SDL, Inc. The compact thermo-electric cooler (TEC) packaged device is capable of 1-W out...
متن کاملdiffraction-limited beam and quantum noise measurements in a continuous-wave laser-diode-pumped Nd:YAG MOPA system
We describe a Nd:YAG slab laser master oscillator power amplifier (MOPA) system that has been scaled to 104 W of output power at 1064 nm, single transverse mode. The amplifier system consists of rod amplifiers followed by edgeand end-pumped slab amplifiers. The MOPA output of 104 W was 89% fundamental TEM00 spatial mode with less than 3% depolarization. These results are a key milestone in the ...
متن کاملHigh Gain Solid-State Amplifiers for Picosecond Pulses
Picosecond solid-state lasers are attractive for many industrial and scientific applications, such as precision material processing (Dausinger et al., 2003; Breitling et al., 2004), nonlinear optics (McCarthy & Hanna 1993; Ruffling et al., 2001; Sun et al., 2007) and laser spectroscopy (Mani et al., 2001). In contrast with traditional laser processing performed with 10-100 ns multi-kHz sources,...
متن کاملCoherent power combination of two Master-oscillator-power-amplifier (MOPA) semiconductor lasers using optical phase lock loops.
Using heterodyne Optical Phase-Locked Loops (OPLLs), two 1W high power 1550 nm master-oscillator-power-amplifier (MOPA) semiconductor lasers operating as current controlled oscillators are phase-locked to a 1 mW reference laser. The signals of the two MOPAs are then coherently combined and their mutual coherence is studied. In each OPLL, the acquisition range is increased to +/-1.1GHz with the ...
متن کاملLaser assisted emittance transfer for storage ring lasing
In modern storage rings the transverse emittance of electron beams can be comparable to that from state-of-art photoinjectors, but the intrinsic low peak current and large energy spread precludes the possibility of realizing short-wavelength high-gain free electron lasers (FELs) in storage rings. In this note I propose a technique to significantly increase beam peak current without greatly incr...
