Transforming graphite to nanoscale diamonds by a femtosecond laser pulse (HOPG) samples were irradiated by a 100 fs pulse with a center wavelength of

The femtosecond laser is an infrared laser (wavelength: 1,053 nm) with ultra-short pulse duration (10–15 s). Given its short pulse duration, the femtosecond laser has the ability to deliver laser energy with minimal collateral damage to the adjacent tissue.

The SHG output at 515 nm of 350 fs laser pulses has been used at 1 MHz repetition rate and focused with a 50x 0.6NA objective. Devices Menlo Systems’ femtosecond Yb fiber-based laser sources now offer more than 10 W in average To characterize the proposed dual-channel OPO, we initially performed wavelength measurement by tuning the cavity length of each channel individually, as commonly used in femtosecond laser pumped OPOs. 21 It should be noted that coherent coupling between two signals is completely avoided as a result of the cavity design. Femtosecond Lasers and Laser Assisted in Situ Keratomileusis (LASIK) Background. Femtosecond (FS) laser is an infrared laser with a wavelength of 1053nm.

Mode-locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds or femtoseconds. A laser operated in this way is sometimes referred to as a femtosecond laser, for example in modern refractive surgery. The basis of the technique is to induce a fixed-phase relationship between the longitudinal modes of the laser's resonant cavity. Constructive interference between these modes can cause the laser periodicity of the wavelength fringes in a region around l 0 (here assumed to be 1550 nm). Femtosecond laser writing technique enables fabrication of unbalanced Mach-Zehnder interferometers in fused silica substrate.

The instrument will allow tailoring of the time-frequency spectrum of femtosecond pulses generated by seeded free-electron lasers (FEL) and high-harmonic generation (HHG) sources down to a central wavelength of ~15 nm.

Femtosecond (fs) lasers are ultra-short pulse width lasers (10-15 s), generated through a process known as mode locking. Mode-locked lasers utilize phase locking to interfere a large number of lasing modes together in such a way as to cause the generation of ultrafast laser … With thousands of femtosecond lasers deployed in demanding applications, Spectra-Physics delivers highest reliability for dependable multi-year operation to advance micromachining production applications. Ultracompact, air-cooled, fixed wavelength femtosecond lasers: 250 fs A single-laser source with dual-beam-mode output may open up new research fields of nonlinear optics and quantum optics. We demonstrate a dual-channel scheme to generate femtosecond, dual-wavelength, and dual-beam-mode tunable signals in the near infrared wavelength range.

In fact these circuits, written in glass, can be perfectly mode-matched at telecom wavelength to the in/out coupling fibers, which is a key requirement for a low-loss processing node in future quantum optical laser source, thus making fiber-based laser sources the obvi-ous choice.
