“…This is common practice in electrically-driven semiconductor devices and has been used in particular for devices used for micro-displaytype projection/display applications [103,104]. Recent pulsed pumping experiments [105,106] have shown that this method improves the maximum output power achievable with a given SDL chip as long as the pulse duration is shorter than a few hundred nanoseconds, the typical transient time associated with SDL heating.…”

“…The technological hurdles associated with this are essentially to create a uniformly-pumped 100-to-400 μm-diameter disk and to overcome thermal heating effects. In the main [103,104,150], the latter issue is addressed through the thin-device cooling approach and the use of pulsed pumping. As for the former challenge, two radically different approaches have been proposed to-date (see Fig.…”

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.

“…An integrated OPSL system has been demonstrated by Osram, with wall-plug efficiencies of about 5%. 14,15 Second-harmonic generation of laser-diode emission directly uses either surface-emitting lasers (VCSELs) 16 or edge-emitting laser diodes. The use of VCSELs has advantages for large-volume manufacturing, since surfaceemitting devices allow for wafer-level testing, a straightforward mounting technology, and direct power-scaling by array schemes.…”

Abstract— The unique advantage of projection displays is the ability to produce large images from small devices. The use of lasers as the projection light source will mean a further step in terms of compactness as well as efficiency for projection systems. However, the advent of laser projection is currently still limited by the availability of low‐cost green lasers. Blue‐diode‐pumped solid‐state lasers are one promising way to realize green as well as red lasers that are specifically suited for projection applications. An efficient solid‐state laser that is based on Pr3+:YLF as the laser material, pumped by a blue‐laser diode and emitting at 523 nm, is presented here. The laser reaches power‐conversion efficiencies of more than 7% and output powers of up to 378 mW at green wavelengths. By making only minor modifications to the laser resonator, a red laser emitting at 640 nm can be realized within the same setup. An output power of 166 mW at a power‐conversion efficiency of 6.9% is demonstrated in the red. By combining a red‐ and a green‐emitting blue‐diode‐pumped solid‐state laser with another blue diode, an integrated RGB projection light source can be realized that is based on a single‐diode technology.

Virtually all projectors sold for professional or consumer applications use HID lamps as a light source. The most common lamps are ultra‐high pressure mercury lamps for most applications and xenon lamps for high‐end applications. New light sources including lasers, LEDs and microwave‐powered electrodeless lamps are challenging the dominance of HID lamps. This paper highlights the advantages and limitations of projection light sources, including example applications.
