“…Basing on a conventional two-mirror cavity consisting of EM and OC, a spectral filter (SF) was inserted intra-cavity after the Tm:YAG/Ho:YAP crystal for separating the intra-cavity Tm laser from the Ho laser. This SF was coated HR at Tm laser (R>99.5% at 1.9 ~2.02 μm) and AR at Ho laser (T>97% at 2.05 ~2.1 μm), which means the Tm laser can be confined between EM and SF for intra-cavity pumping, without being modulated by the saturable absorber (SA) and leading to the failure in Q-switching [29]. We define the current cavity structure as hybrid cavity because the cavity for Tm laser (consisting of EM and SF) and the cavity for Ho laser (consisting of EM and OC) were coupled.…”

“…which have been grown and demonstrated to be promising hosts for Tm and Ho ions at 2 μm [23]- [27]. Furthermore, although Q-switching by directly using the pulse modulation elements were limited in the intra-cavity pumping scheme due to the inevitable self-pulsing [21], [28], feasibility in achieving regular Q-switching pulsing can be explored according to the recently proposed hybrid cavity by spectrally separating the Tm laser from the Ho laser intra-cavity, where maximum average power of 474 mW at 2090 nm in a composite Tm/Ho:YAG laser has been reported [29].…”

The outstanding chemical and physical properties of 2D materials, together with their atomically thin nature, make them ideal candidates for metaphotonic device integration and construction, which requires deep subwavelength light–matter interaction to achieve optical functionalities beyond conventional optical phenomena observed in naturally available materials. In addition to their intrinsic properties, the possibility to further manipulate the properties of 2D materials via chemical or physical engineering dramatically enhances their capability, evoking new science on light–matter interaction, leading to leaped performance of existing functional devices and giving birth to new metaphotonic devices that were unattainable previously. Comprehensive understanding of the intrinsic properties of 2D materials, approaches and capabilities for chemical and physical engineering methods, the resulting property modifications and novel functionalities, and applications of metaphotonic devices are provided in this review. Through reviewing the detailed progress in each aspect and the state-of-the-art achievement, insightful analyses of the outstanding challenges and future directions are elucidated in this cross-disciplinary comprehensive review with the aim to provide an overall development picture in the field of 2D material metaphotonics and promote rapid progress in this fast emerging and prosperous field.

Nonlinear optics is an important research direction with various applications in laser manufacturing, fabrication of nanostructure, sensor design, optoelectronics, biophotonics, quantum optics, etc. Nonlinear optical materials are the fundamental building blocks, which are critical for broad fields ranging from scientific research, industrial production, to military. Nanoparticles demonstrate great potential due to their flexibility to be engineered and their enhanced nonlinear optical properties superior to their bulk counterparts. Synthesis of nanoparticles by laser ablation proves to be a green, efficient, and universal physical approach, versatile for fast one-step synthesis and potential mass production. In this review, the development and latest progress of nonlinear optical nanoparticles synthesized by laser ablation are summarized, which demonstrates its capability for enhanced performance and multiple functions. The theory of optical nonlinear absorption, experimental process of laser ablation, applications, and outlooks are covered. Potential for nanoparticle systems is yet to be fully discovered, which offers opportunities to make various types of next-generation functional devices.
