“…This nonlinear conversion efficiency is lower than 8 %/W achieved in [71], with the difference mainly caused by the beam quality of the fundamental laser. The beam quality of the generated green light was close to diffraction limited with M 2 < 1.3.…”

“…Also, external cavity broad area diode laser systems have been demonstrated to be suitable for frequency doubling. Power levels of more than 100 mW has been achieved [71], [72]. Using either external cavity tapered diode lasers or master oscillator power amplifier configurations, up to 600 mW of light have been obtained in the blue spectral region with up to 4 W of fundamental input power [19], [73]- [75].…”

“…Indeed, GaN-based edgeemitters with M 2 ∼ 3 are already commercially available with powers up to 1 W at 405 nm and 0.5 W at 445 nm [108] and progress on wavelength extension towards green emission is well underway [109,110]. Alternatively, single-pass frequency-doubling of an external-cavity stabilised broadarea edge emitter [111] or of an amplified distributed feedback laser [112] have been shown to produce 142 mW and 600 mW of 488 nm radiation, respectively.…”

Recent developments in semiconductor disk lasers (SDLs) generating visible or ultraviolet light are reviewed. After an introduction on potential applications, we discuss how the combination of vertical-emitting semiconductor GaAs-based structures and intra-cavity nonlinear conversion techniques can be successfully exploited to uniquely meet demands for continuous-wave radiation in the visible and ultraviolet spectral range. To do so, an overview of the device operating principles and performance is presented highlighting the underlying material considerations, semiconductor structural designs, thermal management techniques and suitable cavity configurations. This summary is completed by a presentation of new developments in the field, with a particular focus on the trends towards miniaturization.Green-pumped direct-red-emitting Semiconductor Disk Laser.

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. PPLN waveguide crystal pumped by a DFB laser (above). Integrated SHG device on a CCP heatsink (below).
