Description- Innovative diode-pumped, self-seeded master oscillator design achieves SLM output without external narrow linewidth seed diodes or cavity-locking electronics.
- Stable master oscillator cavity ensures TEM₀₀ spatial mode output, resulting in excellent beam properties after amplification.
- Models with improved Gaussian fit are available for applications requiring a smooth, near-Gaussian beam profile.
- Linear amplifiers provide a cost-effective solution for high energy nanosecond systems, with advanced beam shaping for smooth, hotspot-free spatial profiles.
- Low light depolarization enables efficient generation of up to the 4th harmonic with optional built-in harmonic generators.
- Angle-tuned non-linear crystal harmonic generators in temperature-stabilized heaters are used for second, third, and fourth harmonic generation, with high spectral purity and manual or optional motorized wavelength switching.
- Low optical pulse jitter with respect to the Q-switch trigger allows reliable synchronization with external equipment.
- System control is available via control pad, USB, LAN, and optional RS232, with Windows-compatible software.
