Generation of Visible Radiation in Periodically Poled, Nearly-Stoichiometric Lithium Tantalate
Stoichiometric lithium tantalate (SLT) has been identified as a promising alternative to congruent lithium niobate as substrate material for quasi-phasematched (QPM) nonlinear optical frequency conversion. The advantages of SLT include superior resistance to optical damage, greater ultraviolet transparency, and a lower coercive field which should facilitate the fabrication of thicker periodical...
متن کامل1.34-μm Nd:YVO4 laser mode-locked by SHG-lens formation in periodically-poled stoichiometric lithium tantalate.
Self-starting, steady-state χ((2))-lens mode-locking of a 1.34-μm diode-pumped Nd:YVO(4) laser using intracavity second harmonic generation in PPMgSLT is demonstrated. Pulses as short as 3.6 ps with an average output power of ~1 W are obtained at a repetition rate of 120 MHz.
متن کاملHigh-power picosecond Nd:GdVO4 laser mode locked by SHG in periodically poled stoichiometric lithium tantalate.
Periodically poled stoichiometric lithium-tantalate is used for mode locking of a diode-pumped Nd:GdVO(4) laser by intracavity second-harmonic generation. Stable and self-starting operation is observed achieving average output powers of up to 5 W at a pulse-repetition rate of 107 MHz. The obtained pulse durations range from 6.5 ps at maximum output power down to 3.2 ps at 1.4 W.
متن کاملVapor-transport equilibrated near-stoichiometric lithium tantalate for frequency-conversion applications.
Near-stoichiometric lithium tantalate (SLT) crystals were produced from congruent lithium tantalate by a vapor-transport equilibration process. Because of the resultant increase in photoconductivity and reduction in photogalvanism, the crystals showed no observable photorefractive damage at 514.5 nm up to the highest intensity used, 2 MW/cm2. The crystals also exhibited low green-induced infrar...
متن کاملEfficient periodically poled stoichiometric lithium tantalate optical parametric oscillator for the visible to near-infrared region.
A compact, efficient optical parametric oscillator (OPO) for the visible to near-infrared region based on periodically poled stoichiometric lithium tantalate pumped by a frequency-doubled multikilohertz Q-switched Nd:YAG laser is demonstrated. Up to 61% photon conversion with a 71% slope efficiency for photon conversion from 532 nm to the signal radiation was measured. We observed that the effi...
