75W Output Power Diamond Cutting Laser Diode Pump Module with
Nd:YAG Rod
Description
HTOE DPL-1064-S3-*075 is a diode side-pumped Nd:YAG laser module with 75W output power at
1064nm centerwavelength. It’s an ideal engine to drive high-end
DPSS laser systems. With a 3mm diameter, 78mm length rod and
special symmetrical pumping structures, the gain modules deliver
low-rank beam profile with excellent beam quality and serve to be
used in both resonator and amplifier designs.
LD side-pumped laser module is high power laser module, which is
easy to be integrated into customer's laser systems. Adopting laser
diode arrays as pumping sources, it has the advantage of high
electro-optical conversion efficiency, reliable performance,
compact size, etc. It’s core device of all-solid-state laser could replace traditional
lamp-pumped condenser cavity. It provides high quality pumping
sources for industrial processing and scientific applications.

Principle
Side pumping is a technique of optically pumping a laser gain
medium (usually of a solid-state laser), where the pump light is
injected from the side, i.e. in a direction which is roughly
perpendicular to that of the laser beam. For example, Figure 1
shows a side-pumped rod, where pump light from diode bars is
injected through slits in an otherwise reflecting outer surface
around a laser rod. Figure 2 shows a laser setup containing a
side-pumped rod. An alternative approach is pumping along the laser
beam (→ end pumping).

The key advantage of side pumping is that it allows the use of pump
sources with very low spatial coherence, such as arc lamps or
high-power diode bars. Also, side pumping makes it easy to combine
multiple pump sources. It is possible e.g. to pump a rod laser with
several diode bars (side-by-side) which have fast axis collimation
only; the total width of the emitting region can approach the rod
length. Another advantage is that the absorbed pump power can be
smoothly distributed in the longitudinal direction. For such
reasons, side pumping is often used for high-power solid-state
lasers.
