Abstract

Seven output wavelengths ranged from violet to mid-infrared have been observed simultaneously from a optical parametric oscillator with a periodically poled lithium niobate crystal. The pump laser is diode-pumped Q-Switched Nd:YVO₄ laser with the wavelengths at 1064 nm. The turning output wavelengths can be obtained by changing the periods or temperatures of PPLN. The seven output wavelengths, corresponding to the sum frequency generation of the pump and the doubling signal ( 2ω_s+ω_p), the third harmonic generation of the signal ( 3ω_s ), the second harmonic generation of the pump (2ω_p), the sum frequency generation of the pump and the signal (ω_s+ω_p), the second harmonic generation of the signal (2ω_s), the signal (ω_s) and the idler (ω_i), measured are 433, 488, 532, 616, 731, 1463 and 3902 nm, at the period of 28.7 μm with the temperature of 333 K. These data showed good agreement with those calculated by the Sellmeier equation. This phenomenon may find novel applications in photonic devices.
