DILAS offers the widest range ofdiode laser conduction-cooledheatsink configurations in the market.

Operating conditions can be
CW or QCW for the water-cooled,uncollimated and water-cooled,fast-axis collimated types. In addition,
both axis collimation is available inCW. At nearly maximum output power
levels, the extremely efficient coolingpermits duty factors up to 50%.
DILAS builds diode laser vertical stacks
up to 70 bars within the industry’s
toughest tolerances. Our advanced
housings, optics’ mounting and online
sensoric-testing give you full control.

Applications
MedicalDefense

Medical applications cover the whole
diode laser spectrum, starting withphotodynamic therapy (PDT) in thevisible wavelength range at 630nm690nm. Cosmetic applications like hairremoval, skin rejuvenation and varicose
vein removal are achieved within
the 800nm to 1000nm wavelength
range. This wavelength also applies
to the dental and surgical treatment.
Dermatological applications at 1470nm
as well as further medical applicationsin the range of 1550nm, 1940nm to2200nm complete the spectrum.

For defense, wavelength andoperational parameter requirements
vary significantly from application toapplication. Beside established usageof lasers in range finding and target
designation, key hot areas are eyesafe diode lasers used in a number ofapplications. Other areas are wide-field
illumination, high-energy lasers, as well
as homeland security detection andinstrumentation.

Diode-Pumped Solid-State Lasers
Covering rod-laser, disk laser and fiber
laser pumping, pumping of solid-statelaser material is the dominant laser
application in the industrial field.
Visible red is used with Cr doped lasermaterial. Other lasing materials suchas Tm, Nd:Yb and Er require longer
pumping wavelengths in the rangeof 700nm to 1000nm. Additionally,pumping wavelengths at 1470nm
and 1532nm require specific output
solid-state laser wavelengths.
Non-solid-state materials such as
Rubidium or Cesium vapor can also
be pumped by diode lasers.

Graphic Arts
Using diode lasers for imaging ofsheet-fed printing plates, is a methodfor fast producing printing plates
while avoiding the time consuming andnon-environmental friendly chemicalprocesses. These computer-to-plate(CTP) and direct-on-press (DOP)
technologies are widely used in modern
printing processes.
Materials Processing
DILAS supports customers all over
the world in a wide range of different
applications, including plastics welding
in automotive and medical device
manufacturing. Soldering in electronics
and the automotive industry, solderingin photovoltaic applications, aswell as hardening of metals are also
potential applications.
