Abstract: The possibility of pulse repetition rate multiplication by a high factor was demonstrated in a ring optical parametrical oscillator intracavity synchronously pumped by a picosecond modelocked Nd:YVO4 laser. The multiplication factor was controlled and scaled up to 26 by an optical parametrical oscillator and pump cavity length detuning. A pulse repetition rate of 2.12 GHz was achieved at a wavelength of 1.54 μm and an improvement of the coupled laser stability was observed. This system can be of interest for s… Show more

“…An important factor in the development of ps OPOs is the exploitation of practical high-power pumping sources. Until now, ps OPOs have been pumped by mode-locked solid state lasers, such as Nd:YAG, [3−5] Nd:YVO 4 , [6,7] Ti:Sapphire lasers, [8] and fiber lasers. [9−11] Recently, a laser diode array (LDA) pumped Innoslab amplifier system has attracted researchers' attention for its excellent thermal management, which is attractive in practical applications.…”

We demonstrate a high-efficiency mid-infrared picosecond optical parametric oscillator (OPO) based on MgO doped periodically poled lithium niobate (MgO:PPLN) with a laser diode array (LDA) pumped Innoslab amplifier as the pumping source. Under a 16 W synchronously pumping power, 4.5 W of idler light at 2896 nm is obtained. A tuning range of idler light from 2688 nm to 3016 nm is achieved, within which the highest optical-optical conversion efficiency from pump power to OPO output is 35.1%. Moreover, a signal light of ∼500 mW from 1644 to 1700 nm with a repetition rate of 233.8 MHz is generated.

We analyze the dynamics of mode-locked pumped solid-state lasers focusing on the transition between mode-locked and CW behavior. Where the ratio of the pump and laser cavity lengths is a rational number, 'rational-harmonic mode-locking' is obtained. When the cavity length is detuned away from such resonances, modulated continuous output is generated. The transition from mode-locked to modulated CW operation is explored experimentally for a Ce:LiCAF laser operating at 290 nm and pumped by a 78.75 MHz mode-locked frequency quadrupled Nd:YVO(4) laser. Both CW output and mode-locked output with pulse repetition rates up to 1.1 GHz were achieved. A rate equation model is developed to predict optimum cavity lengths for achieving CW output with minimized modulation.

The research and development of laser systems for intracavity phase interferometry is described. These systems are based on an intracavity synchronously pumped optical parametric oscillator (OPO), enabling the generation of two trains of picosecond pulses inside a single cavity. In such a configuration, it is possible to measure the beat note frequency between two pulses and to very precisely determine the phase difference between them. The pump source is a diode-pumped passively mode-locked Nd:YVO4 laser. A periodically poled magnesium-doped lithium niobate crystal is used as the optical parametric oscillator crystal coupling the pump and the signal cavities. We designed a synchronously pumped OPO in a linear and ring cavity configuration allowing generation in a dual-pulse regime. By a mutual detuning of both cavity lengths, the quasi-synchronous regime of pumping was achieved and high harmonics of repetition rate frequencies were generated. Such a system can be useful for applications such as pump-probe spectroscopy or for testing telecommunication systems. We also realized the subharmonic OPO cavity as a source of two independent trains of picosecond pulses suitable for intracavity phase interferometry; we also measured the beat note signal.
