2016 September 5
Altechna has been named a National Champion for Lithuania in The European Business Awards, sponsored by RSM; Europe’s largest business competition set up to celebrate business excellence and best practice in the European business community.

Laser Power control units

2016 February 28

Altechna presents technical overview of extra cavity laser power control methods realizable with free space optics. It is intended to help industrial laser processing engineers to make the right choice of attenuator design for their laser processing systems.

Particular methods come with distinctive advantages as well as drawbacks. For instance, neutral density reflective type filters with optical density gradient over the cross-section grants a rather even attenuation over wide spectral range from UV to NIR, however they are susceptible to laser damage.

This white paper covers several options of output power control through manipulation of the polarization along with its’ superiorities and shortcomings of individual components, e.g. waveplate vs. EO modulator, and peculiar features of various polarizers used in setups of the kind. Unpolarized laser power control solution is also introduced with schematic layout and attenuation properties.

Laser capability to accomplish extremely precise tasks by applying high power impact within tiny spatial domain, e.g. diffraction limited spot, has lead laser power control to become an important variable that helps to optimise yield and secure successful completion of the task.

Femtosecond optics

2015 May 12

The market for femtosecond optics has grown over the decades since the introduction of first sub-picosecond lasers in 1990s but it still remains quite small compared to longer pulse or CW lasers and all the optics available for such lasers. Conventional optics and coatings will inevitably end up by either distorting the temporal characteristics of the pulse, being damaged by high peak power of the pulse, or both.

Optical materials possess a specific quality when the phase velocity of light inside the material dependent on the frequency (or wavelength), or equivalently when the group velocity depends on the frequency. This is called chromatic dispersion or group-velocity dispersion (GVD). The latter is measured in units of s²/m or fs²/mm. It’s most convenient to define GVD for optical materials (glasses, fibers etc) in order to evaluate how much your pulse will stretch or compress by using different thickness/length of material. For optical components an alternative measure called the group delay dispersion (GDD) is used. GDD characterizes dispersion for the optical whole component without the need to take thickness/length into consideration.

GDD is usually an unwanted effect because streched ultrashort pulse will lose it’s two main properties: it will no longer be ultrashort and it’s peak power will distribute withint the streched pulse (please refer to figure 1). Usually, the only case where pulse streching is a sought-after effect is in ultrashort pulse amplifiers which streches the pulse, amplifies it and compresses it again.

A quick guide on how to choose laser crystal cut

A quick guide on how to choose laser crystal cut

2014 April 11

When choosing laser crystals one has to decide which crystal cut to use, i.e. how the end faces of the crystal will be cut. Generally, there two different cuts are used in laser crystals: right-angle cut and Brewster-angle cut.

Right-angle cut and Brewster-angle cut

Fig. 1. Right-angle cut (a.) and Brewster-angle cut (b.) of Ti:Sapphire laser crystal. L stands for crystal length.

Figure 1 shows the visual difference between the two cuts in Titanium doped sapphire crystals: right-angle cut has the polished ends perpendicular to the axis of propagation of light; whereas Brewster-angle cut crystals are at Brewster’s angle between the normal vector of the polished face and axis of light input. In the figure this angle is 60.4°. For laser beam propagation from air to laser crystal (with refractive index n), Brewster’s angle is defined as θB=arctan(n). At Brewster’s angle, the surface reflectance is zero for the light with polarization inside the plane defined by the direction of light propagation and the normal to the surface (also defined as p-polarized light).

Right-angle cut is easier to manufacture than Brewster-angle cut, however it leads to higher resonator losses. It is convenient for application of anti-reflective, high reflection or partial reflecting coatings, but is not very useful in high power, especially short-pulse, applications. Coatings applied to the crystal usually have lower damage threshold than uncoated Brewster-angle cut crystal faces.

Brewster-angle cut is used to eliminate reflection losses, increase polarization contrast, avoid formation of parasitic pulses in ultra-short pulse oscillators or even induce negative dispersion. Brewster cut faces are left uncoated in order to increase damage threshold of the surface. Reflection loss of p-polarization is Brewster-angle cut crystals is zero.

Brewster-angle cut crystals are more expensive than right-angle cut crystals because the former require more raw material to get the same crystal length L.

Table below summarizes the differences between the two cuts

  Right-angle cut Brewster-angle cut
Price Lower Higher
Laser induced damage threshold Lower, if dielectric coatings are applied Higher
Reflection losses Higher, if no AR coatings are applied Zero reflection losses for p-polarized light
Aligning Convenient Inconvenient
Other Additional recurring repolishing/
recoating costs due to damaged
coatings over time
Astigmatism induced under high average
power

As a rule of thumb, right-angle cut crystals are often chosen when the applications require cost effective solution and when the aim of application isn’t to get the maximum output of lasing power, whereas Brewster-angle cut crystals are chosen when the application is to get maximum power output keeping in mind that the polarization of pumping laser has to be parallel to the plane of incidence of the laser crystal for best results.

Z Polarizer

S-waveplate: a Unique Converter Presents New Advantages

2011 August 2
Workshop of Photonics (WOP) together with prof. Peter G. Kazansky’s group from Optoelectronics Research Centre (ORC) at the University of Southampton developed a direct laser writing technique for the production of radial polarization converters also known as S polarizers.

Such radial polarizers would be mainly applied at laser machining, microscopy, optical tweezers as well as Raman spectroscopy systems. Our S polarizers have distinguishing features: they are resistant against high-power laser radiation due to monolithic fused silica window design; anti-reflection (AR) coatings can be applied; and a single element is used both for polarization conversion and generation of higher topological charge optical vortices.



Fig.1 An optical vortex generated using a S polarizer.

WOP's and ORC's laboratories expect to prove significant advantages of S polarizers in laser micromachining, such as decreased spot size and uniformity of light-material interaction regardless of machining direction.


Fig.2 View through polarizing microscope with different polarization orientations

Being a commercialization partner Workshop of Photonics is also looking for integrators and end-users in the fields of laser machining, microscopy and optical tweezers. Testing units are already available, while small scale production of the S polarizer devices is planned for the middle of autumn. Custom development of machining heads and optical assemblies incorporating radial polarizers is possible upon request.

The University of Southampton has already applied for a patent application and has appointed Altechna R&D Ltd. an exclusive commercialization partner.
