PRESS RELEASE

femtoTrain

High Q Laser has introduced femtoTrain Ti:Sapphire, a compact, all-in-one, all diode-pumped, Ti:Sapphire oscillator.

The product offers femtosecond light pulses with a duration of <100fs at a repetition rate of 73MHz and an average power of up to 400mW. It is available at fixed centre wavelengths of 790, 800, 810, 850 or 870nm, respectively. As an option the laser can also be operated at its second harmonic wavelength.

The oscillator incorporates, at a footprint of only 53 by 20cm (7.5cm height), fs-resonator and pump laser in one monolithic housing. No external pump laser is needed and the laser can be easily used for your application. A semiconductor saturable absorber mirror (SESAM) assures passive and self-starting mode locking, offering a robust and stable system. In contrary to KL mode locking, saturable absorber mode locking leads to a very clean pulse train with a side band suppression of more than 50dB.

Due to compact size and high stability it is the ideal femtosecond laser source for nanostructuring applications like Two-Photon Polymerization (2PP) or imaging methods like Two-Photon Microscopy. Additionally, the femtoTrain Ti:Sapphire is successfully used for low noise THz generation due to its clean pulse train.
