“…Two major routes can be distinguished in second-harmonic generation: second-harmonic generation of a diodepumped laser or second-harmonic generation of diode laser radiation directly. In the former, a laser emitting infrared radiation with high beam quality such as a diode-pumped solid-state laser (DPSSL) 4,12,13 or an optically pumped semiconductor laser (OPSL) is pumped by an infrared diode. The infrared radiation is then frequency doubled in a second step.…”

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.

Semiconductor light sources technology has seen tremendous strides in recent decades and a rapidly increasing interest in it. The unique advantages and characteristics of this form of light generation include compactness, high efficiency, and reliability. With these recent advancements, light-emitting diodes (LEDs), laser diodes, and superluminescent diodes (SLDs) have become an indispensable part of our homes, factories, and research facilities. In particular, the sensitivity of the human eye to the visible range of the electromagnetic spectrum ranging from 400 to 700 nm and the wavelength-dependence of optical characteristics of materials make visible light required for a plethora of applications ranging from displays for entertainment, to imaging in the medical field, to light-based atomic clocks. While LEDs are the most commonly found type of semiconductor light sources, laser diodes and SLDs are of special interest due to their higher output optical power, spectral purity, and coherence. In this tutorial, we first go over the main unique characteristics of the different types and configurations of visible-light laser diodes and SLDs and their general structures with a focus on their advantages compared to LEDs. We then discuss the applications in which these characteristics are of great interest in the fields of displays, communication, instrumentation, and photonic integrated circuits.
