Since the invention and further development of lasers in the 1960s, photonics has grown
into a field that permeates virtually every aspect of modern life. As photonics deals with the …

The mid-infrared (MIR) represents a large portion of the electromagnetic spectrum that is
progressively being exploited for an enormous number of applications. Thermal imaging …

ZBLAN (ZrF4‐BaF2‐LaF3‐AlF3‐NaF), considered as the most stable heavy metal fluoride
glass and the excellent host for rare‐earth ions, has been extensively used for efficient and …

Quasi-three-level solid-state lasers using trivalent rare earth ions are efficient sources in the
near-and mid-infrared spectral regions. Their unique properties arise from special energy …

A 24 W liquid-cooled CW 3 μ m fiber laser with a multimode-core Er-doped ZBLAN fiber has
been developed. The output power of 24 W and an optical-to-optical efficiency of 14.5%(with …

A maximum output power of 20.6? W at 2.825? μm from an erbium-doped all-fiber laser is
reported, which we believe is the highest output power for this laser transition in single …

The development of hollow core photonic crystal fibers with low losses over a broad spectral
region in the near IR enabled the demonstration of a novel laser type-Hollow-core Optical …

Enormous performance gains have been made in fluoride-based fiber lasers operating
around 3 μm due to advances in fiber fabrication and improvements in high-power pump …

We have developed a diode-pumped tunable 3 μm fiber laser with a cw output power of the
order of 10 W with the use of an erbium-doped ZBLAN fiber. A tunability range of 110 nm …

An Er^ 3+-doped ZrF_4-BaF_2-LaF_3-AlF_3-NaF (ZBLAN) fiber laser was passively mode-
locked by inserting a Fe^ 2+: ZnSe crystal into the free space part of the cavity. Continuous …
