“…This makes them interesting for telecom pulse sources. However, the repetition rate was limited until recently to values of a few GHz [25] because higher repetition rates make it difficult to exceed the threshold value of the pump peak power of the OPO. By pushing the performance of passively mode-Iocked lasers at 1 /-Lm in terms of power and repetition rate we could develop widely tunable OPOs with 10-GHz pulse repetition rate and high average output powers.…”

“…The major innovations in SPOPOs have been achieved by way of improved pump sources and through the use of quasi-phase-matched (QPM) nonlinear materials, such as periodically poled lithium niobate (PPLN). These developments have led to threshold powers as low as a few milliwatts of average pump power, 2 thus enabling, for example, direct diode-laser pumping 3 and pumping with a fiber laser. 4 In the latter study, a quasi-cw mode-locked fiber laser was used with pump pulses of 20-ps duration at a repetition rate of 85 MHz.…”

A femtosecond all-fiber laser source incorporating a cw mode-locked Yb-doped silica fiber oscillator and amplifier has been used to synchronously pump an optical parametric oscillator based on periodically poled lithium niobate. The signal output, consisting of 330-fs pulses at a 54-MHz repetition rate and average powers up to 90 mW, was tuned from 1.55 to 1.95 mm, with a corresponding idler range of 2.30 3.31 mm.

Abstract. An overview of recent developments in the field of high-power, highbrightness diode-lasers, and the optically nonlinear conversion of their output into other wavelength ranges, is given. We describe the generation of continuous-wave (CW) laser beams at power levels of several hundreds of milliwatts to several watts with near-perfect spatial and spectral properties using Master-Oscillator PowerAmplifier (MOPA) systems. With single-or double-stage systems, using amplifiers of tapered or rectangular geometry, up to 2.85 W high-brightness radiation is generated at wavelengths around 810 nm with AlGaAs diodes. Even higher powers, up to 5.2 W of single-frequency and high spatial quality beams at 925 nm, are obtained with InGaAs diodes. We describe the basic properties of the oscillators and amplifiers used. A strict proof-of-quality for the diode radiation is provided by direct and efficient nonlinear optical conversion of the diode MOPA output into other wavelength ranges. We review recent experiments with the highest power levels obtained so far by direct frequency doubling of diode radiation. In these experiments, 100 mW single-frequency ultraviolet light at 403 nm was generated, as well as 1 W of single-frequency blue radiation at 465 nm. Nonlinear conversion of diode radiation into widely tunable infrared radiation has recently yielded record values. We review the efficient generation of widely tunable single-frequency radiation in the infrared with diode-pumped Optical Parametric Oscillators (OPOs). With this system, single-frequency output radiation with powers of more than 0.5 W was generated, widely tunable around wavelengths of 2.1 m and 1.65 m and with excellent spectral and spatial quality. These developments are clear indicators of recent advances in the field of high-brightness diode-MOPA systems, and may emphasize their future central importance for applications within a vast range of optical wavelengths.What has attracted scientists and engineers most about lasers is, certainly, that strongly directed and monochromatic light beams can be generated with high power. Such radiation with high spatial beam quality and narrow spectral bandwidth is commonly termed high-brightness radiation. The general properties of diode lasers, i.e. small size, robustness, potentially low costs, and their high wall-plug efficiency have so far been the central issues in designing diode lasers for applications.
