Abstract: We present an all-fiber 770 nm laser module based on second harmonic generation (SHG) in a periodically poled lithium niobate (PPLN) waveguide. The laser module provides an output power of ...
Abstract: Fiber lasers with narrow linewidth are essential light sources for many prospects in advanced scientific fields. In this letter, we proposed a scheme of self-injection locked ...
Background: Vestibular migraine (VM) is the most common cause of episodic vertigo, yet its diagnostic markers remain limited. Perception of verticality, measured via static subjective visual vertical ...
