Tunable pulse stretcher for ultrafast lasers

Tunable pulse stretcher for ultrafast lasers

The tunable fiber pulse stretcher is a structural, durable, economical and efficient solution for realizing powerful ultrafast laser systems. Pulse duration can be controlled in chirped pulse amplification (CPA) systems employing Bragg gratings or structured Bragg grating (VBG) compressors. Suitable for high-energy lasers that require more stretching of the pulse before the amplification chain.

The tunable function is used to control the duration of the pulse and compensate for nonlinear effects caused by the amplifier; it also reduces the development cycle of the laser system and compensates for manufacturing differences. Supports customization to achieve powerful ultrafast laser systems.

Product Features:

Precise phase trimming is possible, allowing dynamic pulse control to reach the highest peak power;

Tunable pulse stretchers enable a single laser to operate in both picosecond and femtosecond regimes;

Adjustable pulse stretchers compensate for amplifier-induced nonlinear effects for optimal performance in all energy states;

The all-fiber structure results in a compact and environmentally stable package suitable for a variety of demanding applications.
