A low-threshold efficient KTA OPO by a fiber-coupled diode-end-pumped Nd：YVO_4 laser
A low-threshold efficient high-repetition-rate eye-safe optical parametric oscillator（OPO） is presented.The OPO is based on an x-cut non-critically phase-matched（NCPM） KTA intra-cavity pumped by an acousto-optically（A-O） Q-switched Nd：YVO4 laser.At 10 kHz,the lowest threshold of 0.75 W and the signa...

| Zusammenfassung: | A low-threshold efficient high-repetition-rate eye-safe optical parametric oscillator（OPO） is presented.The OPO is based on an x-cut non-critically phase-matched（NCPM） KTA intra-cavity pumped by an acousto-optically（A-O） Q-switched Nd：YVO4 laser.At 10 kHz,the lowest threshold of 0.75 W and the signal power of 0.6 W are got,corresponding to the single pulse energy of 60 μJ and the peak power of 20 kW.Tuning the frequency,the maximum output power at 1536 nm is 1.03 W at 30 kHz with an optical-to-optical conversion efficiency of 12.26%.The fluctuation of the output power is 2.1% during 2 h operation. |
