Based on the novel OPCPA technology, UltraFlux series tunable femtosecond laser generates 30 fs pulses, which can be automatically tuned in 680–960 nm wavelength range. Less than 10 fs pulses are obtained in a few-cycle operating regime. By employing advantages of ultrafast fiber laser, as well as parametric amplification technologies, up to 0.35 mJ output pulse energy with better than 1% pulse-to-pulse stability at 1 kHz repetition rate is achieved.

Definition: lasers emitting pulses with durations between a few femtoseconds and hundreds of femtoseconds

German: Femtosekundenlaser

Categories: lasers, light pulses

How to cite the article; suggest additional literature

A femtosecond laser is a laser which emits optical pulses with a duration well below 1 ps (→ ultrashort pulses), i.e., in the domain of femtoseconds (1 fs = 10−15 s). It thus also belongs to the category of ultrafast lasers or ultrashort pulse lasers. The generation of such short pulses is nearly always achieved with the technique of passive mode locking.

Types of Femtosecond Lasers

Bulk Lasers

Passively mode-locked solid-state bulk lasers can emit high-quality ultrashort pulses with typical durations between 30 fs and 30 ps. Various diode-pumped lasers, e.g. based on neodymium-doped or ytterbium-doped gain media, operate in this regime, with typical average output powers between ≈ 100 mW and 1 W. Titanium–sapphire lasers with advanced dispersion compensation are even suitable for pulse durations below 10 fs, in extreme cases down to approximately 5 fs. The pulse repetition rate is in most cases between 50 MHz and 500 MHz, even though there are low repetition rate versions with a few megahertz for higher pulse energies, and also miniature lasers with tens of gigahertz.

Fiber Lasers

Various types of ultrafast fiber lasers, which are also in most cases passively mode-locked, typically offer pulse durations between 50 and 500 fs, repetition rates between 10 and 100 MHz, and average powers of a few milliwatts. Substantially higher average powers and pulse energies are possible, e.g. with stretched-pulse fiber lasers or with similariton lasers, or in combination with a fiber amplifier. All-fiber solutions can be fairly cost-effective in mass production, although the effort required for development of a product with high performance and reliable operation can be substantial due to various technical challenges.

Dye Lasers

Dye lasers dominated the field of ultrashort pulse generation before the advent of titanium–sapphire lasers. Their gain bandwidth allows for pulse durations of the order of 10 fs, and different laser dyes are suitable for emission at various wavelengths, often in the visible spectral range. Mainly due to the disadvantages associated with handling a laser dye, femtosecond dye lasers are no longer frequently used.

Semiconductor Lasers

Some mode-locked diode lasers can generate pulses with femtosecond durations. Directly at the laser output, the pulses durations are usually at least several hundred femtoseconds, but with external pulse compression, much shorter pulse durations can be achieved.

It is also possible to passively mode-lock vertical external-cavity surface-emitting lasers (VECSELs); these are interesting particularly because they can deliver a combination of short pulse durations, high pulse repetition rates, and sometimes high average output power, whereas they are not suitable for high pulse energies.

Other Types

More exotic types of femtosecond lasers are color center lasers and free electron lasers. The latter can be made to emit femtosecond pulses even in the form of X-rays.

Important Parameters of Femtosecond Lasers

The key performance figures of femtosecond lasers are the following:

There are, however, various additional aspects which can be important:

Apart from these aspects of the laser itself, the quality of the documentation material, such as product specifications, user manual, etc., can be of interest.
