Amplified Lasers for Ultrafast Applications

Did You Know?

Advanced ultrafast amplifiers combine high power, excellent beam quality, and high repetition rates. Enormously high optical intensities, exceeding 10^16 W/cm^2, can be achieved by focusing such intense pulses in some medium. There are two typical amplification schemes, one using the Chirped Pulse Amplification (CPA) technique and another based on multi-pass pulse amplification through the amplification medium. Ultrafast amplifiers find applications where intense pulses for highly nonlinear processes, such as high harmonic generation, are required or for the acceleration of particles to high energies. They may be used in laser-induced nuclear fusion or for micromachining.

Frequently Asked Questions

An amplified laser is a system where ultrashort seed pulses from an oscillator are temporally stretched, amplified in a gain medium, and then recompressed to achieve much higher pulse energies than the oscillator alone can provide. While a standard ultrafast oscillator typically delivers nJ–pJ pulses at tens to hundreds of MHz, an amplified laser outputs µJ–mJ pulses at kHz–MHz repetition rates, enabling nonlinear optics, micromachining, and high-field experiments.

Overview of Amplified Lasers

Amplified lasers are ultrafast light sources that boost the energy of seed oscillators to deliver higher pulse energies while preserving short pulse durations. On FindLight, amplified lasers span Ti:sapphire, Yb-based, OPA/OPCPA and fiber-based architectures tailored for research and industrial use. These amplified lasers typically operate in the femtosecond to picosecond regime, enabling non-linear optics, precision micromachining and time-resolved spectroscopy.

Typical Specifications of Amplified Lasers

When evaluating amplified lasers as ultrafast light sources, engineers usually focus on several core parameters:

  • Central wavelength: Commonly around 800 nm for Ti:sapphire amplified lasers and 1 µm–1.05 µm for Yb-based and fiber amplified lasers; frequency conversion can extend coverage into the UV or mid-IR.
  • Pulse duration: From sub-30 fs up to several picoseconds, depending on compressor design and gain medium.
  • Pulse energy and average power: From microjoule-level amplified lasers for tabletop experiments to multi-millijoule, multi-watt systems for demanding industrial and scientific setups.
  • Repetition rate: Ranging from single-shot and kHz-class amplified lasers up to hundreds of kHz or low MHz for high-throughput processes.
  • Beam quality and stability: M² near 1 for precise focusing, with low timing jitter and excellent energy stability critical for pump–probe experiments.

Use Cases for Amplified Lasers

Amplified lasers on FindLight support R&D in ultrafast spectroscopy, multi-photon microscopy, high-harmonic generation and strong-field physics. In manufacturing, these amplified lasers are used for cold ablation micromachining of metals, semiconductors and transparent materials, as well as scribing, drilling and thin-film patterning where minimal heat-affected zones are required.

Buyer Guidance on FindLight

When selecting amplified lasers, first match the wavelength and pulse duration to your process window or experimental regime. Compare pulse energy, average power and repetition rate to ensure sufficient photon flux and throughput. Review beam quality, synchronization options and noise performance if integrating amplified lasers into pump–probe or multi-laser setups.

On FindLight you can quickly compare specifications across multiple amplified lasers, review datasheets and vendor notes, and request quotes directly from suppliers. Use the platform to ask technical questions about integration, dispersion management and system footprint. All quote requests for amplified lasers can be submitted without registration, streamlining procurement for both engineering and R&D teams.
