LD Side-Pumped Nd:YVO4 532 nm Quasi-Continuous Green Laser

Abstract

Nd:YVO4 remains a preferred gain medium for compact green solid-state lasers because its linearly polarized output simplifies intracavity frequency doubling.

A side-pumped geometry can be attractive in quasi-continuous systems when thermal loading and package volume must be balanced.

The resulting 532 nm output is useful in display, marking, pumping, and laboratory instrumentation.

Performance characteristics

The side-pumped resonator route supports quasi-continuous 532 nm generation with a solid-state cavity format.

By using Nd:YVO4 as the gain medium, the system benefits from efficient diode pumping and a polarization state that is favorable for harmonic conversion.

This approach is well aligned with applications that need green output and stable engineering integration.

Application value

Quasi-continuous 532 nm sources are useful in pumping, biomedical instrumentation, alignment systems, and visible-light processing.

The side-pumped Nd:YVO4 approach is also relevant when a compact module must maintain good conversion behavior over sustained operation.
