Pulsed laser Indylit 20

femtosecondmulti-pulsefiber

Overview
The INDYLIT 20 is an industrial femtosecond laser for material processing. Key nominal parameters: 1030 / 515 nm (with SH option), pulse duration 400 fs – 4 ps (tunable), up to 20 W average power, internal repetition rate 100 kHz – 1 MHz (down to 30 kHz in Burst Mode). The product is designed as a maintenance-free, turn-key, passively air-cooled laser with high stability and dust protection.

Standout features:

• Extremely robust and stable
• Adjustable repetition rate, pulse duration, and power
• High pulse energy and clean pulse shape
• Passively air cooled (water cooling optional)
• Maintenance-free and turn-key
• Protected against dust

Applications:

• Materials microprocessing
• Ophthalmology
• Semiconductor and electronics
• Display manufacturing
• Battery manufacturing
• Black marking

Robust design and no maintenance
The Indylit 20 features an innovative patented passive cooling design that ensures high stability of optical parameters such as pulse duration, beam pointing, and power. Mechanical construction is designed for robustness and protection against dust. An optional built-in second harmonics (SH) module provides wavelength extension for broader material processing applications.
