“…One of the special tunable sources is wavelength-sweeping fiber laser, in which the central wavelength can be tuned periodically. To achieve the periodical and stable tuning operation, the active sweeping devices such as electric-driven PZT, heater or the scanning tunable filter have been utilized in the majority of modern lasers [4][5][6][7][8]. In recent years, a kind of spontaneous sweeping fiber laser based on so-called selfsweeping or the self-induced laser line sweeping effect was found and deeply studied.…”

Generally speaking, the self-sweeping effect relies on the dynamical grating formed in active fiber. Here, the normal self-sweeping was generated in a ytterbium-doped fiber which serves as a fiber saturable absorber and is introduced to the laser cavity by a circulator in this experiment. The sweeping rate and the sweeping range alter as usual, both of which can be controlled by the pump power. Further, a new self-pulse signal is observed and discussed, which shows both the grating feature and saturable absorption of YDFSA. Our work provides a new self-sweeping way and can act as a platform to further deeply study this effect.

Rare Earth elements (RE) play an important role in the high-tech industry. Displays, fine electronic devices, sensors, optoelectronics, and many other fields rely on the use of these elements to deliver the technology we depend on. The possibility of improving the capacity of all these applications is attractive and there are a few ways to achieve that, one of them is to purify the REs to get only one isotope. Given that, one of the few techniques able to separate RE isotopes is the Atomic Vapor Laser Isotope Separation (AVLIS) which is the technique used in the Brazilian facility for isotope separation via laser. In this work we are going to show the latest results on the Brazilian AVLIS applied to enrich dysprosium. As a preliminary result, it was observed an enrichment by means of a mass spectrometer coupled to the experimental setup and a thin film was collected with an enrichment factor of 1.37 (163Dy).

“…Accordingly, free-space broadband parametric sources were developed but such sources usually require complex alignement and are often considered as bulky and costly systems. To circumvent this, great effort has been dedicated to the development of ultrafast lasers emitting directly in the MIR region, such as fiber lasers around 2.8-3.1 µm [9][10][11][12][13] and Fe:ZnSe lasers centered around 4.4 µm [14][15][16] . While Fe:ZnSe lasers can produce mJ pulses with durations as short as 150 fs 16 , they still require multiple free-space components and complex alignement.…”

A tunable ultrashort soliton pulse source reaching up to 4.8 µm is demonstrated based on a 2.8 µm femtosecond fiber lasercoupled to a zirconium fluoride fiber amplifier followed by a small core indium fluoride fiber.This demonstration is extendingby 500 nm the long wavelength limit previously reported with soliton self-frequency shift (SSFS) sources based on fluoridefibers. Our experimental and numerical investigation highlighted the spectral dynamics associated with the generation of highlyredshifted pulses in the MIR using SSFS enhanced by soliton fission. This study is intended at providing a better understandingof the potential and limitations of SSFS based tunable femtosecond fiber sources in the 3-5 µm spectral range.
