By virtue of its narrow pulse width and high peak power, the femtosecond pulsed laser can
achieve high-precision material modification, material additive or subtractive, and other …

A tunable ultrashort soliton pulse source reaching up to 4.8 µm is demonstrated based on a
2.8 µm femtosecond fiber laser coupled to a zirconium fluoride fiber amplifier followed by a …

Optical parametric oscillators (OPOs) and Raman lasers are two nonlinear-based laser
technologies that extend the spectral range of conventional inversion lasers. Power and …

We demonstrate a Ti: Sapphire laser generating in excess of 1.2 W in continuous-wave
operation when pumped directly with four green laser diodes eliminating the need for a …

We use pump beam wavelength and polarisation to demonstrate that the phenomenon of
pump-induced loss in Ti: sapphire is linked to simultaneous excitation of two separate …

In blue GaN‐based laser diodes with a 40 μm broad‐ridge waveguide, lateral modes of
different order are selectively observed by high‐resolution spectroscopy combined with …

Abstract Large scale Dy: YAlO 3 (Dy: YAP) crystals with different doping concentrations were
grown by the Czochralski methods. To our knowledge, the effects of as-grown crystals on the …

A wide variety of applications require high peak laser intensity in conjunction with a narrow
spectral linewidth. Typically, injection-locked amplifiers have been employed for this …

Microcombs—generated by coherently pumping nonlinear microresonators—have emerged
as a state-of-the-art scheme at the chip scale. Dual-comb spectroscopy (DCS) technology …

In the past, there were limited efforts to use light-emitting diodes (LEDs) for pumping solid-
state lasers. However, these attempts were overshadowed by the introduction of laser …
