“…The conversion efficiency from fundamental to signal light increased from 49% to 62% with the PRFs varied from 60 kHz to 20 kHz. This conversion efficiency is much higher than our previous work based on Nd:YVO 4 -KTA OPO (40%) [14] and other relative reports about intracavity OPO [8][9][10][11][12]. The adoption of mode mismatch compensating resonator improved the conversion efficiency.…”

A high power eye-safe optical parametric oscillator driven by the LD end-pumped Nd:YAlO3 laser was demonstrated based on a non-critically phase-matched KTiOAsO 4 crystal. The mode mismatch compensating resonator was adopted for efficient OPO conversion. The maximum output power of 2.3 W at 1562 nm was achieved at the pulse repetition frequency of 20 kHz. The conversion efficiency between the fundamental light and the signal light was up to 62%, which was much higher than other relative reports.

“…The lower PRR means higher peak power of single pulse. The best frequency repetition rate was determined by whether the increased number of fundamental pulses or the decreased peak power of fundamental pulses was predominant when increasing the frequency repetition rates of A-O Q-switcher in the process of IOPO [19].

A simultaneous dual-wavelength eye-safe laser at around 1.9 and 1.7 μm based on only a single KTiOAsO4 (KTA) intracavity optical parametric oscillator (IOPO) is firstly reported. The dual-wavelength-IOPO is driven by an acoustooptic (AO) Q-switched Nd:YAG laser, which is simultaneously oscillated at the radiations of 1.3 and 1.06 μm. Within the KTA-IOPO cavity, the signal output waves of IOPO at the wavelength of 1.9 and 1.7 μm are pumped by the 1.3 and 1.06 μm radiations from Nd:YAG laser, respectively. With the laser diode pumped power of 100 W and the pulse repetition rate of 4 kHz, the maximum average output power of 1.3 W at 1895 nm with the pulse duration of 30 ns and that of 0.9 W at 1715 nm with the pulse duration of 18 ns are obtained. With different diode pump power, the central wavelength of IOPO signal light at 1.9 μm is tunable from 1850 to 1895 nm, while the other signal wave at 1.7 μm is from 1650 to 1715 nm. The output power of 1.9 μm and 1.7 μm versus the pulse repetition rate (PRR) at the diode-pump power of 100 W

“…For the Q-switched Tm 3+ or Ho 3+ doped lasers the output pulses have wide pulse width [6], while for the near-degenerate OPOs it tends to output dual wavelengths around 2 μm as it is difficult to make the signal and idler beam having exactly the same wavelength without particular wavelength choose optics as volume Bragg grating [9], [10]. Nowadays noncritical phase matching (NCPM) KTA or KTP -OPOs pumped by the Q-switched Nd 3+ -doped lasers are widely investigated for generating signal light at 1.5 μm [11]- [13]. Recently, our group has demonstrated such an OPO with an output power of 4.4 W and a conversion efficiency of 18% [14], [15].…”

We propose an experimental technique for efficient 2-µm light generation based on the intracavity noncritical phase matching optical parametric oscillator (OPO). Intra-cavity pumped by a diode pumped actively Q-switched Nd:YVO 4 laser operating at 1.3 µm, we have achieved efficient 2093-nm signal beam emission making full use of noncritical phase matching KTA-OPO. At a diode pump power of 9.8 W and a Q-switching repetition rate of 30 kHz, a signal beam with a spectral linewidth of ∼1 nm and an average power of 1.01 W have been obtained, giving a diode pump power to signal power conversion efficiency of 10.3%. The short pulse width of ∼3.4 ns is achieved, which is much shorter than other approaches with Q-switched operation to generate 2-µm laser beams.Index Terms-2 µm laser, noncritical phase matching, KTA crystal, optical parametric oscillator (OPO).
