چکیده

Mid-infrared radiation near 2.8 mum was generated by difference-frequency generation in an 80-mm-long periodically poled Ti:LiNbO(3) channel waveguide by pump radiation near 1.55 mum (tunable external-cavity laser) and a signal radiation of 3.391 mum (HeNe laser). We obtained a normalized conversion efficiency of 105% W(-1) , which is to our knowledge the highest value ever reported.

Infrared radiation generated by quasi-phase-matched difference-frequency mixing in a periodically poled lithium niobate waveguide

We report quasi-phase-matched difference-frequency generation of 2.1 pm radiation at room temperature using the & nonlinear coefficient in a periodically poled lithium niobate channel waveguide. A tunable Ti:A1203 laser (ilzO.8 ,um) and a Nd:YAG laser (I = 1.32 pm) were the pump and signal sources, respectively. With 160 mW of 0.81 pm and 1 mW of 1.32 pm radiation coupled into the waveguide, 1....

Mid-infrared difference-frequency generation in periodically poled KTiOAsO(4) and application to gas sensing.

Tunable mid-infrared radiation (3.45-3.75 microm) with a power level of 0.14 microW is generated by quasi-phase-matched difference-frequency mixing of a Nd:YAG laser and a tunable-diode laser (near 1.5 microm) in multigrating periodically poled KTiOAsO(4) . The wavelength and temperature bandwidths are approximately 65 nm cm and approximately 62 degrees C, respectively. The temperature-tuning s...

Tunable terahertz-wave generation from DAST crystal by dual signal-wave parametric oscillation of periodically poled lithium niobate.

The first known demonstration of tunable terahertz-wave generation by difference-frequency generation of dual signal-wave quasi-phase-matched optical parametric oscillation was performed with periodically poled LiNbO(3) (PPLN) with a series of gratings. An organic ionic salt, 4-dimethylamino-N-methyl-4-stilbazolium-tosylate (DAST), was used as a nonlinear crystal. A compact terahertz-wave sourc...

Tunable midinfrared source by difference frequency generation in bulk periodically poled KTiOPO4

We demonstrate quasi-phase-matched difference frequency generation in periodically poled KTiOPO4. A midinfrared ~3.2–3.4 mm! idler with a power level of 0.17 mW is generated by mixing a Nd:YAG laser and tunable external cavity laser near 1550 nm which is amplified by an erbium-doped fiber amplifier. The wavelength, temperature, and angle tuning characteristics of this device are determined. The...

Broadband-signal wavelength converter with high damage resistance.

Uniform MgO-doped near-stoichiometric LiNbO(3) was successfully grown from Li-rich melts by a melt supplying technique. Periodically poled domains were demonstrated in MgO-doped near-stoichiometric LiNbO(3) wafers. Efficient quasi-phase-matched difference frequency generation was achieved in a titanium-diffusion waveguide based on periodically poled MgO-doped near-stoichiometric LiNbO(3). The c...
