  1. Due to our continuous product improvement program, specifications are subject to change without notice.
  2. FemtoTrain is a Class IV - High-Power Laser, whose beam is, by definition, a safety and fire hazard. Take precautions to prevent exposure to direct and reflected beams. Diffuse as well as specular reflections can cause severe skin or eye damage.


High Pulse Energy

femtoTrain is specifically designed for applications that require high pulse energy and peak power at a high repetition rate. This laser allows fast scanning or process speeds with a repetition rate of 10 MHz and pulse energy of >500 nJ. The femtoTrain platform is optimized for low noise and outstanding long-term stability and is the ideal laser source for sensitive bio-imaging and micro-surgery applications. The pulse is near-transform limited and thus does not need dispersion pre-compensation.

High Reliability

femtoTrain is developed, designed and manufactured with high reliability and quality in mind. The laser is equipped with long life diodes and features a sealed optical cavity, manufactured in a clean room production environment. The result is a dependable laser with long lifetime, high uptime and low cost of ownership. With direct diode pumping technology and an ultra-stable optical cavity design, femtoTrain offers easy-to-use and proven 24/7 operation.

Compatible Power Sensors

To verify and analyze the output power of your FemtoTrain laser, we recommend the Ophir F80(120)A-CM-17 (7Z07103) thermal power sensor and Centauri laser power meter.  Additional information on this laser measurement equipment can be found on the ophiropt.com website.  Other Ophir sensors and meters may also be suitable for the FemtoTrain, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
