“…Vibration and rotation of many types of molecule in biology and organic chemistry can be detected by a laser in this area [1]; for instance, water has a strong absorption peak at 2.9 µm. A wide range of laser sources have been invented aiming at this wavelength range [3][4][5][6][7][8][9], including diode pumped optical parametric oscillators, solid state lasers, and semiconductor light sources. However, suffering from their own disadvantages, such as limited opportunity for miniaturization, restricted wavelengths of operation, or requirement for cryogenic cooling, these sources have not been used widely in practice.…”

We have numerically investigated the generation of a fourth order stimulated Raman scattering (SRS) signal in a silicon ring cavity. Output power saturation of the silicon Raman laser has been observed. The influences of effective free carrier life, length of ring cavity and coupling ratio on the signal generation are discussed based on our simulation work. Finally, we put forward a double ring cavity scheme to improve the output characteristics of the silicon Raman laser.

“…The replacement of ubiquitous and time-proven cw dye lasers by all-solid-state sources is an outstanding challenge in laser development. In recent years the evolution of frequency-stable cw optical parametric oscillators (OPOs) as sources of tunable, coherent radiation has progressed rapidly 1,2 and thus these sources may be considered a possible alternative to dye lasers. It has been shown that their wide tuning range, good frequency stability, and high efficiency make them well suited for high-resolution spectroscopy in the near and midinfrared.…”

We demonstrate a cw doubly resonant optical parametric oscillator that is frequency doubled in an external resonant cavity to the visible spectral range. We obtained single-frequency radiation in the range 565-590 nm with as much as 3.8 mW of power, which is continuously tunable over an 18-GHz range and step tunable over 160 GHz. The source is well suited for high-resolution spectroscopy in the visible region. As a demonstration, we performed persistent hyperfine spectral hole-burning spectroscopy of Eu(3+): Y(2)SiO(5) . Reliable operation of the source permitted studies of the hole's lifetime over several hours.

“…Subsequent work thus aimed on increasing the available diode power and to reduce the number of resonant waves, but relied on conventional nonlinear crystals based on birefringent phase matching. With Potassium-Tytanyl-Phosphate (KTP) and Rubidium-Titanyl-Asenate (RTA) crystals diode-pumped DROs were realized [77,78,79,80] and showed an improved stability, tunability and output power. Besides the improvement of the output and beam quality of diodelasers, new crystals with high nonlinearity have been developed.…”

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.
