Ultrafast Femtosecond Laser Spirit® One™

Key Features

  • High average power (>3 W) and high pulse energy (30 µJ)
  • Integrated pulse-picker with analog-in modulation
  • User adjustable pulse duration between 400 fs and 2.5 ps (optional)


Ultrafast Femtosecond Laser Spirit® One™

Spirit® One™ is a new industrial femtosecond laser that delivers game-changing cost-performance. With ultrashort <400 fs pulse width, high pulse energy and average power output, and repetition rate up to 1 MHz, the laser is an It’s in the Box™ laser that combines power supply and laser head in a single rugged, compact and lightweight package for ease of integration. Spirit One enables advancements in high precision applications including microsurgery, femtosecond micromachining, medical device manufacturing, optogenetics, and multiphoton microscopy.

With >3 W average power,>30 µJ pulse energy at 1030 nm wavelength, Spirit One provides additional flexibility with a new adjustable pulse duration option, allowing the user to freely choose pulse durations between 400 fs and 2.5 ps by software in less than 3 seconds. The amplifier is optimized for one factory calibrated repetition rate at either 100 kHz (30 ?J) or 1 MHz (3 ?J) that can be chosen by the customer. Additional or different pre-set repetition rates are optional and can be configured in the factory during assembly on request. The laser includes an integrated pulse picker for fast pulse selection and power control by an analog input signal or via software commands for high process throughput.

Spirit One is based on the proven and widely deployed Spirit industrial femtosecond laser platform and has passed extensive environmental qualification testing to ensure high reliability. Fully automated and computer controlled, Spirit One has exceptional power and beam pointing stability during 24/7 operation, resulting in high precision and reproducibility for demanding applications.
