“…The TAG lens elongates the axial range of imaging, i.e., the depth of view, and consequently provides fast volumetric speed [77]. The axisymmetric acousto-optic device combined with spatial filtering makes it possible to generate the dynamic Bessel beams at ultrahigh speed (Figure 6N) [72]. The mode-locked fiber laser can also be converted to a non-diffracting beam, e.g., an Airy beam through an external cubic phase plate [78], and has been demonstrated at the output wavelength of 1.0 μm.…”

The light propagation in the medium normally experiences diffraction, dispersion, and scattering. Studying the light propagation is a century-old problem as the photons may attenuate and wander. We start from the fundamental concepts of the non-diffracting beams, and examples of the non-diffracting beams include but are not limited to the Bessel beam, Airy beam, and Mathieu beam. Then, we discuss the biomedical applications of the non-diffracting beams, focusing on linear and nonlinear imaging, e.g., light-sheet fluorescence microscopy and two-photon fluorescence microscopy. The non-diffracting photons may provide scattering resilient imaging and fast speed in the volumetric two-photon fluorescence microscopy. The non-diffracting Bessel beam and the Airy beam have been successfully used in volumetric imaging applications with faster speed since a single 2D scan provides information in the whole volume that adopted 3D scan in traditional scanning microscopy. This is a significant advancement in imaging applications with sparse sample structures, especially in neuron imaging. Moreover, the fine axial resolution is enabled by the self-accelerating Airy beams combined with deep learning algorithms. These additional features to the existing microscopy directly realize a great advantage over the field, especially for recording the ultrafast neuronal activities, including the calcium voltage signal recording. Nonetheless, with the illumination of dual Bessel beams at non-identical orders, the transverse resolution can also be improved by the concept of image subtraction, which would provide clearer images in neuronal imaging.

“…The framerate of the currently used SLM is limited to 60 Hz, which is not enough to enable real time light-sheet adaptation. In contrast, DMDs feature framerates of more than 10 kHz [32][33][34]. Thus, for a field of view of 500 µm and a framerate of 50 Hz, totally 200 beams can be adapted laterally in steps of 2.5 µm within only 20 ms.…”

In light-sheet microscopy, a confined layer in the focal plane of the detection objective is illuminated from the side. The illumination light-sheet usually has a constant beam length independent of the shape of the biological object. Since the thickness and the length of the illumination light-sheet are coupled, a tradeoff between resolution, contrast and field of view has to be accepted. Here we show that scanned Bessel beams enable object adapted tailoring of the light-sheet defined by its beam length and position. The individual beam parameters are obtained from automatic object shape estimation by low-power laser light scattered at the object. Using Arabidopsis root tips, cell clusters and zebrafish tails, we demonstrate that Bessel beam light-sheet tailoring leads to a 50% increase in image contrast and a 50% reduction in photobleaching. Light-sheet tailoring requires only binary amplitude modulation, therefore allowing a real time illumination adaptation with little technical effort in the future.

“…A variety of methods have been proposed for generating the bottle beam, such as diffractive optical elements [9], computer-generated hologram [19], axicon [23], moiré techniques [24], speckle pattern [25] and spatial light modulator [26]. Recently, some researches have been studied a microscale nonparaxial optical bottle beams [27], a dynamic bottle beams [28] and a terahertz bottle beam [29]. In addition, owing to surface plasmon polaritons'(SPP) unique properties, it can simultaneously generate SPP Bessel-like beams and bottle beams [30].…”

The dynamics of the inward-focusing ring Airy beam in nonlocally defocusing nonlinear media is investigated in detail, and a bottle beam shape can be observed by adjusting the amplitude of the inward-focusing ring Airy beam and the nonlocality of the media. The gradient force of the bottle beam is numerically studied. It is worth mentioning that the bottle beams are formed in the nonlinear regime, which indicates that much higher intensity is allowable for these beams than those in the linear regime. Our approach and results may pave the way to the optical tweezers in the nonlinear regime.
