Wavelength tunable, 264 J laser diode array for 10 Hz/1ms Yb:YAG pumping

Tunable multiterahertz beat signal generation from a two-wavelength laser-diode array.

We report, for the first time to our knowledge, generation of a tunable miltiterahertz modulation signal on an optical carrier directly from a single laser source. The modulation frequency, which can be tuned from 0.15 THz to more than 7 THz, is the beat note obtained by varying the spectral separation between the coaxial two-color output of a two-wavelength laser-diode array from 0.32 to 17 nm...

Quantum well intermixed tunable wavelength single stripe laser diode

A single waveguide laser with two separately addressed sections is fabricated using selective area intermixing of InGaAsP multiple quantum well grown on InP substrate. The selective intermixing of quantum wells is achieved by capping the two sections with PECVD grown silicon nitride and silicon dioxide respectively followed by rapid thermal annealing the device at 750°C for 30s prior to the fab...

1450-nm high-brightness wavelength-beam combined diode laser array.

We have demonstrated wavelength beam combining of a 1450-nm diode laser array with a novel smile compensation method. We have achieved 20-W cw from a 25-element single bar with an M(2) of 1.9 (fast axis) x 10 (wavelength-beam-combined dimension).

Continuous wave, 30 W laser-diode bar with 10 GHz linewidth for Rb laser pumping.

A laser-diode bar incorporated into an external cavity with a volume Bragg mirror produced 30 W of cw output power within a 20 pm (10 GHz) spectral linewidth (FWHM) centered at 780 nm. The device output power exceeded 90% of that for the free-running laser-diode bar. The emission wavelength was tuned over a 400 pm range without broadening laser spectrum width. Absorption of 90% of the laser rad...
