AI Article Synopsis

  • Scientists created a special type of laser called a dual-wavelength laser that can change colors and works on a special material called erbium-doped lithium niobate.
  • This laser can tune its output very precisely, with a range of 11.875 GHz, which is important for making clear signals.
  • The design of this laser allows it to be made smaller and could lead to new advancements in technology that uses light, like communication systems.

Article Abstract

We demonstrate a monolithic tunable dual-wavelength laser fabricated on erbium-doped lithium niobate on an insulator (Er:LNOI). The dual-wavelength laser enables independent tuning with a continuously linear electro-optic (EO)-modulated tuning range of 11.875 GHz at a tuning efficiency of 0.63 pm/V. Tunable microwave generation within 50 GHz with a maximum extinction ratio of 35 dB is experimentally demonstrated by further exploring the charge accumulation effect in LNOI. The monolithic design of this work paves the way for microscale integration of laser devices, presenting significant prospects in photonics research and applications.

Photoacoustic microscopy (PAM) is a high-resolution and non-invasive imaging modality that provides optical absorption contrast. By employing dual- or multiple-wavelength excitation, PAM extends its capabilities to offer valuable spectroscopic information. To achieve efficient multispectral PAM imaging, an essential requirement is a light source characterized by a high repetition rate and switching rate, a ≈microjoule pulse energy, and a ≈nanosecond pulse duration.

Background: Photobiomodulation therapy (PBMT) has been showed to have beneficial effects on the healing and control of inflammation associated with oral surgical wounds. However, different PBMT protocols have been proposed and it is not clear if different protocols impact the hard and soft tissues healing equally.

Purpose: To compare the tissue repair of postextraction alveoli of third molars between treated with dual-wavelength PBMT (red and infrared) or PBMT with infrared laser (IRL) alone.
