COHERENT COUPLING OF MULTIPLE LASER DIODE ARRAYS BY INJECTION ...- coherent coupling laser diodes ,COHERENT COUPLING OF MULTIPLE LASER DIODE ARRAYS BY INJECTION LOCKING. Award Information. Agency: Department of Defense. Branch: Defense Advanced Research Projects ... Shop Couplings For Industry - MISUMI Configurable ComponentsA long-standing challenge for semiconductor lasers is scaling the optical power and brightness of many diode lasers by coherent beam combination. Because single-mode semiconductor lasers have limited power available from a single element, there is a strong motivation to coherently combine the outputs of many elements for applications including

The complex component of the coupling coefficient j ¼ j r þ ij i, used to describe the coupling between adjacent semiconductor microcavity laser diodes, is studied. The complex component j i represents the gain or loss difference between the coherent in-phase and out-of-phase array supermodes obtained from two laterally coupled lasers.
Contains specifications of several commercial lasers and allows the user to calculate far field divergence angles and near field spot size values for typical laser diodes One of the main uses of this calculator is to lookup or calculate values to use in the custom pattern generator since most laser diode specifications list far field divergence in degrees while Optiscan works with the spot ...

The RWLD series of laser diodes are available in a wide range of wavelengths, power levels, and packages. The RWLD wavelength options span from 405nm to 1650nm, with output powers in the range of 10 mW to 300 mW, packaged in a TO-18 package with photodiode. Custom wavelengths, powers, and packages upon request.
A phase-locked diode-laser system based on master-slave coupling of two-dimensional vertical-cavity surface-emitting laser (VCSEL) arrays by injection locking is presented. Frequencies and phases are adjusted by laser-trimmed microresistors. Additional beam-transformation optics consisting of two diffractive optical elements (DOEs) and a Fourier lens concentrates most of the far-field power in ...

Eric Zhao. Mechanical Engineer, Formulatrix Inc. An ultrafast femtosecond laser is an essential tool for two photon imaging. We have successfully integrated ALCOR laser with our Sonicc protein crystallization imaging system. ALCOR laser is well engineered, very reliable, and easy for OEM integration.
Coherent diode lasers at the four hair removal wavelengths all exhibit the same slope, simplifying power balance. These different wavelengths are generated by different diode laser materials and until recently, this has created difficulties for system builders because the slope (output versus current) was different for each of the wavelengths.
The use of non-coherent light diodes is becoming more popular as a stand-alone therapy as well as in combination with laser diodes in the same emitter. The North American Association of Laser Therapy (NAALT) places both laser and non-laser light therapies under the umbrella term 'phototherapy.

Most of the important demonstrations of highly efficient and high-power SWIR fiber lasers involved the Tm3þ ion, because of the favorable ion interactions that produce high quantum efficiencies, and the compatibility of this laser with commercial diode laser excitation is presented in Chapter 7.
We report experimental demonstrations of the use of a photorefractive barium titanate ring passive phase conjugate mirror in the coherent coupling of two GaAlAs diode lasers. By cooling the crystal towards its tetragonal to orthorhombic phase transition, we were also able to achieve infrared photorefractive phase conjugation with gain.
We report and analyze the supermode switching with current injection found for coherently-coupled dual-element vertical cavity surface emitting laser arrays. The output power, spectral characteristics, and far-field mode profile are measured for a range of bias current operating conditions. The coupling-induced enhanced output power from an in-phase or out-of-phase supermode is confirmed when ...

Two separate laser diodes emitting near 980 nm were coupled by a thick volume Bragg grating recorded in a photothermorefractive glass. The coupled diodes emitted at the same wavelength with a spectral width narrowed to below the resolution of the spectrum analyzer ( <30 pm). Coherent emission at a pumping level greater than five times above the threshold was observed for several months with ...
