Femtosecond Lasers for Material Processing and Micromachining Applications

 

 

Short pulsed Femtosecond laser  applications are continually growing and being developed across a variety of market spaces including micromachining, bio, medical, and research & development.  Ultrafast lasers are primarily utilized in applications where the required HAZ and quality cannot be achieved by a traditional CW or long pulsed fiber or nanosecond and picosecond laser systems.  RPMC Lasers Inc. offers a range of Femtosecond laser systems with power levels up to 50W and pulse durations <120fs and repetition rates from single shot to several MHz’s.

Femtosecond Lasers

A femtosecond is equal to 10 to the −15 of a second, which is one millionth of one billionth, of a second. At a given pulse energy, the peak power of the laser increases as the pulse width gets shorter.  Therefore, femtosecond lasers have much higher peak power than longer pulsed picosecond, nanosecond, or millisecond pulsed lasers.  These higher peak powers result in higher removal rates in a given material due to the fact that more of the total energy is transferred to the material and less is pulled into heating the material.  The high peak powers of these femtosecond lasers, often several MW, creates a breakdown between the electrons and atoms in the material, causing what is known as a “Coulomb explosion”.  A Coulomb explosion is a cold processing alternative to the conventional thermal ablation utilized by longer pulsed lasers. Ablation is a thermal process that relies on local heating, melting, and vaporization of molecules and atoms. Ablation can be detrimental for some laser applications as it typically creates unwanted HAZ, recast and burs, all of which are negative effects of heat making cold ablation a better option.

Micromachining with Femtosecond Lasers

The primary application for femtosecond lasers is micromachining, which can include consumer, medical or R&D applications.  Typically, these applications require femtosecond pulses for their cold-ablation affects.  Femtosecond lasers are ideal tools for applications where micro-cracks, heat affected zones (HAZ), or recasts are detrimental to the integrity or lifetime of the material being processed.  

A growing application for femtosecond lasers is in the field of handheld electronics...more specifically cell phones and tablets.  Manufactures are experimenting with different materials to make a more robust product.  The popularity of ultrafast femtosecond lasers continues to grow in these challenging industrial applications that require cold ablation.

Our femtosecond micromachining lasers can be applied to a variety of industrial processes, including cold ablation, semiconductor processing, stent cutting, laser marking, TFT repair, thin film patterning, marking, dicing, scribing, solar cell cutting, edge isolation, laser deposition, surface patterning, processing volatile materials, or machining hard materials. Femtosecond lasers are also used in various medical procedures within the ophthalmological and dermatological fields

Femtosecond lasers microstructure (groove, cut, drill, micromill, etc.) virtually any material with:

  • no thermal side-effects such as microcracks, burrs, or recast
  • lateral features as small as a few um
  • pulses-on-demand for easy integration into delivery systems
  • high average power, pulse energy and rep rate for increased ablation rate per pulse

Examples for industrial femtosecond laser micromachining can include:

  • IMD – medical and biomedical devices (PMMA, PLLA, catheters, stents, pacemakers, guidewires, cutting, drilling, de-coating, etc.)
  • FPD- flat panel display (AMOLED, OLED, Quantum Dots panels)
  • Micro and nano-processing of complex materials (glass, ceramics, quartz, sapphire, organic tissues, etc.)
  • Surface texturing

Application lab services are available for proof or principle testing.  Please contact RPMC Lasers for more information.

Y-Fi: Femtosecond Laser

The Y-Fi laser series is a family of high average power, high repetition rate near-IR ultrafast fiber lasers. Y-Fi products are based on a single rugged opto-mechanical platform and are engineered for hands-free operation.
Y-Fi Outstanding Characteristics
Y-FI Femtosecond Laser

Y-Fi Overview

  • Wavelength: 1035nm
  • Pulse-width: <190fs
  • Output-power: 4.5W, 20W, 50W
  • pulse-energy: 0.45uJ, 3uJ, 40uJ
  • Rep-rate: 0.5 - 15, 60MHz
  • q-switch-type: Active

The short, clean pulses of the Y-Fi laser series deliver more peak intensity per mJ than competing products. KMLabs guarantees both pulse duration and pedestal energy content, verified with a FROG pulse measurement, to ensure each laser pulse is free of picosecond background that robs energy from the main short pulse. Thus, more of the laser output is truly usable, requiring less energy/average power
and decreasing the probability of seeing collateral damage and other detrimental interactions.
