High-Power Diode Laser Technology XVI.
In the most developed fiber amplifiers, optical pump power is introduced into the ~400μm-diameter, 0.46NA first cladding of the double-clad, Yb-doped, gain fiber, using a (6+1):1 multi-mode fiber combiner. For this configuration, the core diameter a

Copper-based micro-channel coolers (Cu-MCC) are the lowest thermal-resistance heat-sinks for high-power laserdiode (LD) bars. Presently, the resistivity, pH and oxygen content of the de-ionized water coolant, must be actively controlled to minimize c

We present a fiber-coupled pump-module emitting more than 1kW of mode-stripped power at 976nm from a detachable 225µm, 0.22NA fiber. The electrical-to-optical efficiency at 1kW is ~50%. Six of these pump modules attached to a (6 + 1):1 multimode com

We present a novel, high-power stack of 20% fill-factor, 976nm, laser-diode bars, each directly attached to an enhanced lateral-flow (ELF), copper-based, water-cooled heat-sink. The heat-sinks contain mounting screws that form a kinematic mount to mi

Herpes simplex virus (HSV) typically causes mucocutaneous disease, encephalitis, and acute men ingitis. There have been no previous reports of chronic meningitis due to this virus. A case of chronic meningitis due to herpes simplex virus type 2 (HSV-

High brightness, laser-diode bars are required for efficient coupling into small-core optical-fibers. Record power and brightness results were achieved using 20% fill-factor, 980nm, 1cm-wide, 4mm cavity-length bars. Lifetimes of single bars, operated

A record, 250W, CW output-power has been achieved for a single, 1cm-wide, 3.5mm cavity-length, 20% fill-factor, 976nm, laser-diode bar operated at 20°C. The remarkable laser-bar performance was in part the result of a novel EPIC (Enhanced Performanc
