Quasi-phase-matched parametric fluorescence in room-temperature lithium tantalate waveguides.

We report what is to our knowledge the f irst observation of quasi-phase-matched parametric fluorescence in the 1.2-2.3-microm region, at ambient temperature, in lithium tantalate waveguides, using a pump wavelength between 805 and 845 nm.

Fabrication parameter optimization of a low-threshold high-efficiency proton-exchanged waveguide laser in Nd:LiTaO(3).

Knowing the correlation between the Nd(3+) excited-state lifetime in proton-exchanged waveguides and the phase diagram of the H(x)Li(1-x)TaO(3) compound permits optimized waveguide fabrication parameters to be found. These have been used to produce a Nd:LiTaO(3) waveguide laser with a threshold of 2.9 mW and a slope efficiency of 33%, in good agreement with the best predicted values.

Tunable IR laser source with optical parametric oscillators in series.

A tunable IR laser source is described. A Q-switched Nd:YAG laser at 1.064 µm is used to pump two optical parametric oscillators (OPO's) in series.

Low-loss and low-drive-voltage electro-optical phase modulator at 10.6 microm.

We present the experimental performance of a 16-mm-long phase modulator in the 10.6-microm wavelength range using the electro-optical effect in a InP/Ga(0.47) In(0.

Nd:MgO:LiNbO(3) waveguide laser and amplifier.

We report efficient operation of a channel waveguide laser and a channel waveguide amplifier in Nd:MgO:LiNbO(3). For the laser a cw output power of 2.9 mW was obtained for 23.
