Compact Fiber coupled CW Diode Bars at 808 nm

QD-C1yzz- FI4 & QD-C1yzz- Fhty

DESCRIPTION

The new QD-C1yzz-FL(|) & QD-C1yzz-FH(|) series are equipped with an ultra compact and leakproof package.

Operation wavelength is in the wavelength window 808 nm.

These products integrate highly performing micro optics. Optical power, up to 40W CW, is delivered through a

single multimode fiber terminated by a SMA connector. Small fiber diameter and low numerical aperture lead

to high brightness and high optical power density.

The low profile package, QD-C1yzz-FL(|) {only 38cm3), is proposed with red pilot beam or PIN photodiode as

options.

The low thermal resistance of the assembly allows efficient heat transfer and thermal regulation.

These products are ideal for applications which request high brightness sources for efficient pumping solid-

state lasers, medical applications, material processing, micromachining...
