Abstract: | We present in this report an efficient KTP-based intracavity optical parametric oscillator driven by a diode-pumped Nd:GdVO4/Cr:YAG passively Q-switched laser. For the first time, a novel folded cavity configuration was employed to set the KTP and
Cr:YAG crystals separately at different fundamental beam waists. Based on the ABCD-matrix theory and by taking the thermal
lens effect into account, the laser cavity was well optimized to enhance the OPO performance. A diode pump threshold as low
as 1.2 W and a maximum signal (1.57 μm) average output power up to 560 mW have been achieved. Efficient energy transfer in
the IOPO leads to short pulse duration (1.8–2.6 ns) and high peak power (6.8 kW) output at 1.57 μm. Additionally, the correlation
dynamics between the pump laser and the OPO was analyzed in detail. |
