PRELIMINARY DATA
HIGH POWER CW LASER
DIODE with PELTIER-COOLING
L8413
Compact Peltier-cooling type
FEATURES
High optical power : 20 W/bar
High stability
Long life
High cost performance
Compact
APPLICATIONS
Pumping source for solid state lasers
Materials processing
Welding
Soldering
Medical systems
High power laser diodes with a Peltier cooler feature several advantages such as high stability with long life and high
cost performance with compact structure. Sinve they are designed to be small, they are easily applied as light source to
pump solid state lasers, for material processing like welding or soldering, and for medical systems. The lasing areas
consist of small laser emitters arranged in line and are thus called “Bar” structure. By stacking Bars as a module, a high
power CW operation can be achieved. Water-cooling and Funryu-cooling (patent pending : Japan 8-139479, WO
00/11717) are also available. And focusing lens is available as an option.
