Application into long-range atmospheric sensing using the white-light laser pulse has been carried out [11]. One could take advantage of the temporal deformation to compress the pulse into a few energetic cycle pulses [12]. Laser pulse picker UP2 in set-up with timing generator pMaster 4.2 allows to select single femtosecond pulses from the train at up to 2 Mhz rate.

Only within two decades after the invention of the laser the duration of the shortest pulse shrunk by six orders of magnitude from the nanosecond regime to the femtosecond regime. Nowadays femtosecond pulses in the range of 10 fs and below can be Femtosecond laser pulse delivered by fiber cable. The FD Series is uniquely designed to deliver femtosecond laser pulses via an optical fiber cable to the user application.

He is one of the most hard  Femtosecond laser pulses are used for the ablation of metals and dielectrics (2D and 3D structures), structural changes of materials, optical changes or mechanical processing such as cutting, drilling or milling in order to replace mechanical machining tools. From: Laser Growth and Processing of Photonic Devices, 2012 A central building block for generating femtosecond light pulses are lasers. Only within two decades after the invention of the laser the duration of the shortest pulse shrunk by six orders of magnitude from the nanosecond regime to the femtosecond regime.

Femtosecond laser pulse

Although it was originally introduced in ophthalmology for use in LASIK eye surgery, femtosecond lasers have become widely used in a variety of eye surgeries and have become a preferred tool in many surgical eye procedures. pulses, polarization etc. Optical properties of the ripple-textured metal surface are changed and this can be employed to blacken the metals to enhance light absorption. In our work, ripples were formed on a stainless steel surface using femtosecond Yb:KGW laser (pulse duration 300 fs, pulse repetition rate 100 kHz) operating at 515 nm wavelength.

Laser The laser system used for the experiment is a commercial titanium-doped sapphire (Ti:Sa) laser amplifier Spectra Physics Spitfire Pro XP) pumped by a Ti:Sa oscillator (Coherent Micra-5). Key parameters are: Table 1. Laser parameters Laser parameters Value Pulse duration, fs 50-150 Peak power, GW 30 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 (which also include picosecond lasers ). Femtosecond laser pulse delivered by fiber cable.

We investigate femtosecond pulse generation from a CW Laser diode by optical gating with a Mach-Zehnder electro-optic modulator. 45 ps pulses are amplified to ten’s of watt peak power and propagated through a standard polarization maintaining fiber to reach enough spectral broadening by self-phase-modulation. The shortest optical pulses generated directly in lasers (passively mode-locked titanium–sapphire lasers) have durations around 5 fs, corresponding only to a few optical cycles (few-cycle pulses). Pulse compression techniques applied to similar pulses reach pulse durations of very few femtoseconds, and high harmonic generation even allows the generation of attosecond pulses. Tailored femtosecond laser pulses from a computer-controlled pulse shaper were used to optimize the branching ratios of different organometallic photodissociation reaction channels.
