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.
