Product Description
Cr4+:YAG Laser Crystal Rod Overview
Cr4+:YAG (Yttrium Aluminum Garnet doped with Chromium) is a high-performance passive Q-switch crystal designed for advanced laser applications. This crystal enables ultra-short pulse generation and high repetition rates in diode-pumped laser systems.
Key Performance Features
- Generates pulse widths as short as 5ns for diode-pumped Nd:YAG lasers
- Supports repetition rates up to 10kHz for diode-pumped Nd:YVO4 lasers
- Enables efficient green output at 532nm and UV outputs at 355nm and 266nm
- High damage threshold exceeding 500MW/cm²
- Excellent thermal conductivity and long operational lifetime
