“…Due to the rather low coercive field, which is about 2 kV∕mm, stoichiometric LiTaO 3 crystal is an alternative for small period (4.6 μm) sample fabrication, and can be used for frequency tripling to obtain blue light at 440 nm [74]. As for KTP, the low-temperature poling technique was exploited for creation of domain period down to 5 μm for efficient single-pass SHG of 460 nm blue light [75].…”

The quasi-phase-matching (QPM) technique has drawn increasing attention due to its promising applications in areas such as nonlinear frequency conversion for generating new laser light sources. In this paper, we will briefly review the main achievements in this field. We give a brief introduction of the invention of QPM theory, followed by the QPM-material fabrication techniques. When combing QPM with the solid-state laser techniques, various laser light sources, such as single-wavelength visible lasers and ultraviolet lasers, red-green-blue three-fundamentalcolor lasers, optical parametric oscillators in different temporal scales, and passive mode-locking lasers based on cascaded second-order nonlinearity, have been presented. The QPM technique has been extended to quantum optics recently, and prospects for the studies are bright.

“…A ridge waveguide preamplifier and a tapered amplifier with an emitter width of 250 μm were used. This setup yielded picosecond pulsed emission at 960 nm with an average power of 2.8 W. Blue emission at 460 nm with an average output power of 250 mW was achieved using a 10 mm PPKTP bulk crystal [122]. In both experiments at least three optical isolators have been used.…”

“…The opto-optical conversion efficiency exceeded values of 15% and the wall-plug efficiency was better than 4%. In contrast to the previously described experiments [121][122][123], no optical isolator between the MOPA and the nonlinear crystal was used resulting in a decreased setup size. However, the thermal management of this setup was challenging because of the temperature difference between the diode laser and the nonlinear crystal.…”

A review about second harmonic generation using edge emitting diode lasers and nonlinear crystals to obtain laser radiation in the blue-green spectral range is presented. Therefore, pump laser radiation with high brightness and narrow bandwidth is necessary. Thus, this review gives an overview of the advances made with distributed feedback and Bragg reflector lasers, tapered lasers and amplifiers as well as external cavity diode lasers and master oscillator power amplifier schemes to achieve high brilliance emission. Since periodically poled materials have enabled high second harmonic conversion efficiencies with low and moderate pump powers, the review is focused on frequency doubling using those materials. The most commonly used materials, their properties and limitations are discussed briefly. Single pass and resonant SHG setups with waveguide and bulk nonlinear crystals are discussed and an emphasis on building compact and integrated devices is made.

“…5,6 Several solutions using the combination of diodes and poled crystals have been presented.

A laser system that is based on second-harmonic generation of a broad area laser diode and provides 23.2 mW of diffraction-limited light with narrow bandwidth is described. It is tunable from 487.4 to 489 nm. The broad area laser diode is frequency stabilized in an external cavity that yields 800 mW of diffraction-limited light. This infrared light is converted into the visible by use of a 1 cm periodically poled MgO:LiNbO(3) bulk crystal with a measured single-pass conversion efficiency of up to 3.6%/W x cm.
