چکیده

A simple result of scalar diffraction theory is used to derive the round trip phase accrual of a plane wave in dye laser oscillators containing gratings. This is used to determine configurations where the standing wave condition is satisfied at the feedback wavelength throughout an angle scan. We find that at least one such exactly synchronous configuration always exists regardless of oscillator type.

Composite Cavity Fiber Laser with Asymmetric Output Intensity and Wavelength

The composite cavity fiber laser (CCFL) is relatively simple in its fabrication, as it is essentially three wavelength matched Bragg gratings in a section of doped fiber. By using internal feedback with unequal sub-cavity lengths, unidirectional CCFLs with significantly asymmetric output power from its two outputs can be achieved. Preliminary results also show that it is possible for the lasing...

Theory of self-frequency detuning of oscillations by wave mixing in photorefractive crystals.

Interesting experimental findings of self-frequencydetuning effects of phase-conjugate mirrors (PCM's) were reported recently. 1-3 A dye laser in conjunction with a passive (self-pumped) phase-conjugate mirror (PPCM) caused an unexplained self-frequency scanning of the laser.1' 2 Another system of a cavity formed by two PCM's also demonstrated a nondegenerate oscillation. 3 Recently4 we present...

Travelling Wave Model of a Multimode Fabry-p Erot Laser in Free Running and External Cavity Conngurations

We report the results of a numerical study of multimode behavior of a Fabry-P erot laser. The model is based on travelling-wave equations for the slowly varying amplitudes of the counterpropagating waves in the cavity, coupled to equations for spatially dependent population inversion and polarization of a two-level active medium. Variations in the material variables on the scale of a wavelength...

Short monolithic dual-wavelength single-longitudinal-mode DBR phosphate fiber laser.

We propose and demonstrate a 5-cm-long monolithic dual-wavelength single-longitudinal mode distributed Bragg reflector (DBR) all-phosphate fiber laser. Strong UV-induced fiber Bragg gratings are directly written in highly Er/Yb codoped phosphate fiber. The separation between gratings is selected as 1 cm to only excite two longitudinal modes in the DBR cavity. By exploiting the spatial hole burn...

Erbium-doped waveguide DBR and DFB laser arrays integrated within an ultra-low-loss Si3N4 platform.

Record low optical threshold power and high slope efficiency are reported for arrays of distributed Bragg reflector lasers integrated within an ultra-low-loss Si(3)N(4) planar waveguide platform. Additionally, arrays of distributed feedback laser designs are presented that show improvements in pump-to-signal conversion efficiency of over two orders of magnitude beyond that found in previously p...
