High-performance Nd: YAG Q-Switched Laser
The Nimma series laser is a compact, high-performance lamp-pumped Nd:YAG nanosecond laser, with pulse energy ranging from 400mJ to 2000mJ@1064nm. This series features a small footprint, excellent pointing stability, high energy stability, and exceptional reliability.
Designed for both scientific and industrial applications, the Nimma series ensures superior beam quality and long-term reliability. It is widely used in applications such as pumping OPO, pumping Ti:Sapphire laser, and pulsed laser deposition.
Key Features
- Excellent beam quality
- Attenuator optional
- Single longitudinal mode seeding optional
- LD indicator light optional
