ABSTRACT
Four-wave mixing is investigated in broad-area diode lasers. Two external fields are injected into the device using a phase conjugation geometry and the nonlinear four-wave mixing signal observed by performing spectrally resolved measurement of the far field. By varying the injection geometry, the excited mode of the broad-area diode can be controlled. The gain nonlinearity generates a conjugate wave within the device, thereby resulting in far-field emission in the conjugate direction. Nonlinear conjugate signal efficiency levels of ∼-21 dB have been observed.

    Abstract. We report frequency locking of a 1083-nm DBR diode laser on a high-finesse Fabry-Perot cavity (F congruent 2800). We used the Pound--Drever FM locking scheme at a modulation rate of 5 MHz. A lock bandwidth of about 1 MHz is obtained by using a three-path servo loop. The laser linewidth...

    A fs regenerative amplifier based on Cr:LiCAF is demonstrated for the first time. With direct diode pumping, 8 μJ of pulse energy are obtained directly from the amplifier. When seeded by an Er-doped fiber laser, the amplified seed pulses are compressed down to 252 fs, limited by residual net...
