Ultrashort pulse lasers emit incredibly brief bursts of light, typically in femtosecond or picosecond durations. These short pulses result from techniques such as mode-locking or q-switching that create a train of ultrafast pulses. The key advantage of ultrashort pulse lasers lies in their extremely high peak power within each pulse. This allows for the generation of nonlinear effects in certain materials and precise material processing with minimal thermal damage, amongst others.

Ultrashort pulse lasers in science

In science, ultrashort pulse lasers are essential for applications in time-resolved spectroscopy techniques, such as pump-probe experiments, transient absorption spectroscopy and time-correlated single-photon counting. These have revolutionized our understanding of ultrafast processes in areas such as bioscience, chemistry and material technology by revealing information about atomic and subatomic processes on femtosecond to picosecond timescales. Time-resolved spectroscopy continues to advance fundamental research and the development of novel technologies.

Ultrashort pulse lasers also find extensive use in multiphoton applications. Their ultra-high peak powers facilitate efficient multiphoton absorption, crucial for two-photon and three-photon imaging, microfabrication, and precise tissue ablation. These lasers have revolutionized fields like neuroscience, biomedical imaging, and material processing, empowering researchers and engineers to explore new frontiers in science and technology.

Some of the main ultrashort pulse lasers are:

• Ti:sapphire lasers which operate in the visible and near-infrared range and are tunable around 700 to 1100 nm
• Ytterbium-doped lasers that emit in the near-infrared often at around 1030 nm
• Neodimium-doped lasers that typically emit at around 1064 nm
• Erbium-doped with typical emission at 1550 nm.

Other lasers such as semiconductor lasers and quantum cascade lasers can also provide ultrashort pulses in the visible and IR.

Tuning the wavelength of ultrashort pulse lasers becomes useful for tailoring the laser output to specific applications. However, despite the versatility of the existing ultrashort pulse lasers, there are numerous wavelengths across the visible to the mid-IR that cannot be accessed since these are primarily limited to the specific gain media of available laser materials. Accessing these wavelengths is possible with broadly tunable sources as optical parametric oscillators.
