Lasers

For many applications power stability is the critical performance factor which will determine the quality of outcomes. Access Laser has developed their Line Tracker feature to provide industry leading average power stability of less than +/- 1%.

The unique Line Tracker software-controlled optical feedback loop enables industry-leading power stability and, for shorter models, wavelength selection.

Watch this short introductory video to better understand how Access Laser can meet this standard on their entire laser product series.

Light Conversion first delivered PHAROS in 2006.

PHAROS lasers are currently used for drilling and cutting various metals, ceramics, sapphire, glass, and material ablation; for mass spectrometry; and with a variety of other applications. All these applications enable cutting-edge products and research. With major industrial customers operating in the display, automotive, LED, medical device manufacturing, and other industries, the reliability of PHAROS has been proven by hundreds of systems in 24/7 production environments.

Optics

Image for optical diffusers

Diffractive optical diffusers​​ are optical components that spread the optical power of incoming light beams. In other words, they diffuse the optical energy of the beam profile, making the energy envelope smoother than the original incoming light beam.

There are many types of optical diffusers, including holographic optical elements and perfectly reflecting diffusers.​​ 

Some common applications include:

  • Aesthetic laser skin treatments, including tattoo removal

  • Laser welding, cladding and annealing with large core (> 100 µm) multi-mode fiber lasers

  • Laser based photolithography at the deep UV, which often employs very high M2 excimer lasers

For more information, contact Holo/Or.

Stimulated Emission Depletion (STED) microscopy is a well-known technique for achieving super resolution in microscopy that enables resolving sub-micron details that are smaller than the diffraction limit of the optical system.

STED microscopy requires the system to be highly precise and accurate; otherwise, overall performance may be severely affected.

Holo/Or’s​​ vortex plates​​ are polarization insensitive and do not require rotation alignment. For all these reasons, they pose the perfect solution for STED systems.

For more information, contact Holo/Or.

Manx Precision Optics (MPO) has just released a new​​ Technical Note explaining the fundamentals of growing films for optical coatings.

Even though the bulk properties of the coating material meet the specifications, the final microstructure is highly dependent upon the intricacies of the film growth process. Issues such as the temperature of deposition, the crystalline phase of the deposited material and moisture in the film among countless other factors are critical to ensuring the quality of the end result. Ignorance about such factors can have catastrophic consequences on coating quality, leading to unwanted shifts in spectral behavior, reduced LIDT, reduced bandwidths or even stress-induced crazing!

Holo/Or presents a new video about beam shaping solutions for laser welding applications.

This video explains:

A phase plate is a diffractive optical element (DOE) that superimposes a certain pre-designed phase profile on an input laser beam. Such a phase profile can be binary (by creating a half-wave delay between certain areas of the phase plate) or continuous (reaching up to a full wave delay). This phase profile transforms the laser intensity profile at the far field (the lens focus) to a different profile.

In cases where the phase is periodic (such as a phase grating), the intensity becomes multiple diffracted orders with controlled separation angles. These are what​​ Holo/Or​​ calls​​ diffractive beam splitters or gratings. In cases where the phase is not periodic, various beam shaping effects occur, depending on the phase profile superimposed by the phase plate.

Some known applications that benefit from the use of a spiral phase plate include:

  • Laser ablation for the removal of layers (passivation in solar panel backsides, for example)

  • Laser cutting of thin foils, or dicing of thin semiconductor wafers

  • Laser multi-hole through drilling
