Past decades have witnessed the generation of new stretchable photodetectors in electronic eyes, health sensing, wearable devices, intelligent monitoring and other fields. Stretchable devices require not only outstanding performance but also excellent flexibility, adaptability and stability. Innovative strategies have been proposed to realize the stretchability of devices. In addition, novel functional materials including zero‐dimensional nanomaterials, one‐dimensional inorganic nanomaterials, two‐dimensional layered materials, organic materials, and organic‐inorganic composite materials with excellent properties are emerging to continuously improve the performance of devices. Here, the recent research progress of stretchable photodetectors in terms of both various design methods and functional materials is outlined. The optical performance and stretchable properties are also comprehensively reviewed. Finally, a summary and the challenges associated with the application of stretchable photodetectors are presented.

“…Several types of wavelength-swept lasers, such as external-cavity semiconductor lasers (ECSLs), dye lasers, distributed Bragg reflector lasers, tunable solid-state lasers, verticalcavity surface-emitting lasers, distributed feedback lasers, and optical non-linear frequency conversion-based lasers have been developed in the last 50 years [13][14][15][16][17][18][19][20][21]. Compared to other types of wavelength-swept laser, ECSL has the prestigious characteristics of a large tuning range, high signal-to-source spontaneous emission ratio, narrow linewidth, and low cost, which is one of the most versatile measuring tools [22][23][24].…”

A high side-mode suppression ratio external-cavity wavelength-swept laser system with a wide mode-hopping free tuning range is developed. The proposed wavelength-swept laser is based on a single-angled facet gain chip in a classical Littman-Metcalf external-cavity configuration using a blazed diffraction grating as the feedback element. The output power, side-mode suppression ratio, and tunable range of the external-cavity wavelength-swept laser system are experimentally measured. Wide mode-hopping-free continuous wavelength tuning range about 100 nm in CL-band with a side-mode suppression ratio of more than 65.64 dB are realized. An output optical power of more than 14.12 dBm over the entire tunable region can also be achieved. The proposed external-cavity wavelength-swept laser system allows simultaneously high side-mode suppression ratio and no mode-hopping tunable radiation, thus opening a door for practical applications such as optical modulation schemes.

“…With these extraordinary characteristics, a considerable amount of literature has been published on diamond Raman lasers (DRLs) in the last decade. The remarkable achievements of DRLs have been incorporated into various Raman laser formats, including deep UV [17], visible [18][19][20][21][22][23], NIR [24][25][26][27][28][29][30] and MIR [31] wavelengths in continuous wave (CW) [32], quasi-CW (QCW) [28][29][30] and pulsed [18,22,[24][25][26][33][34][35][36][37] regimes. For the ns-pulsed DRL, maximum pulse energy of 9 mJ at 1.240 μm with pulse width of 8 ns and conversion efficiency of 24% has been reported by Robert J. Williams at Macquarie University [38].…”

High-power ns-pulsed lasers have been widely used in many significant applications, including laser radar, remote-sensing, biomedicine, industrial process, and military defense. Stimulated Raman scattering (SRS) provides an efficient method for extending the wavelengths of laser radiation. Due to the excellent thermal conductivity, high damage threshold, and high gain coefficient, diamond crystal is considered the most potential SRS material to address laser output in specific wavelength regions with high power, high beam quality, and high conversion efficiency. This paper reviews the advances of ns-pulsed crystalline Raman lasers and particularly emphasizes the progress of ns-pulsed diamond Raman lasers (DRLs) in the past decade. DRL has demonstrated a maximum peak power of 1.2 MW at 1.240 μm with a pulse duration of 8 ns. It can also generate high-energy ns pulses featuring Fourier-limited spectral linewidth. The superior optical characteristics and the mature technology of synthetic diamond crystal will make DRL a promising technique to achieve higher performance ns laser pulses.
