Spirit HE


  • High pulse energy (>120 µJ) and high average power (>16 W)
  • User adjustable repetition rate (single shot – 1 MHz)
  • Integrated pulse-picker with analog-in triggering

The Spirit® HE femtosecond laser is a flexible, high repetition rate one box ultrafast amplifier. With direct diode pumped technology developed by Spectra-Physics, 
Spirit HE’s innovative and simple architecture offers truly unique performance.

Spirit HE offers impressive versatility to serve the needs of industrial and scientific customers. The laser’s high pulse energy (up to 120 µJ) and high average power 
(>16 W) enable femtosecond micromachining applications with high throughput and the best quality. Pulse energy and repetition rate adjustability (single shot to 1 MHz) make Spirit HE an ideal laser source for medical device manufacturing and high aspect ratio drilling. The laser is optimized for one factory calibrated repetition rate – either at 100 kHz (12 W / 120 µJ) or 1 MHz (16 W / 16 µJ). This basic repetition rate can be chosen by the customer. Additional pre-set repetition rates are optional and can be configured in the factory during assembly upon request. The integrated pulse picker offers the possibility for fast pulse selection and power control by an analog input signal. This simplifies the integration of the laser and offers fast process throughput.

The optional, high efficiency Second Harmonic Generation (SHG) module is integrated in the laser head and enables the fabrication of smaller and more accurate structures. The fundamental and SHG output beams are collinear at the laser exit for easy integration and beam delivery. The end user can easily switch between the 
1040 nm and 520 nm outputs by software.

Fully automated and computer controlled, Spirit HE is manufactured with high reliability and quality in mind. Spirit HE’s design is optimized for easy integration and for the superb power and beam pointing stability (typically <20 µrad for 100 hours) during 24/7 operation, ensuring high precision and reproducibility in every application.
