Researchers’ night 2020 at KTU

TYRĖJŲ NAKTIS 2020 (Researchers’ night) – event dedicated for young researchers throughout the whole Europe. More than 30 countries (more than 300 cities) organize this event every year.

In Kaunas University of Technology (KTU) event TYRĖJŲ NAKTIS (Researcher’s’ night) is an annual event organized by KTU SMD, usually attended by few thousand visitors (very motivated high school students, Bachelor, Master and PhD students) who are interested in becoming researchers and scientists.

Visitors attended creative and engineering workshops, observed experiments, and had opportunity to speak to exhibitors from research and technology companies.

3photon exhibited during this event with the goal to present career opportunities for Chemistry and Physics students. Students were able to observe our products showcase: Large dichroic mirrors, gold mirrors, IBS output couplers, IR coated crystals (Fe:ZnSe, CdSe,  AgGaS2) and DKDP Pockels cells.

Infrared coatings – case studies 2020

Infrared coatings

0.75 – 20 µm

Overview, capabilities, case studies

Overview

Infrared coatings on crystals, windows, or optical substrates at 3photon coating facility are deposited every day to produce high quality infrared optical components. IR coated components are used in spectroscopy, medical, military, astronomy applications, in such devices as lasers, thermal imaging gadgets, detectors, etc. There are three main ranges in terms of wavelength:

  • SWIR/NIR (Short wave/Near infrared): 750 nm – 3000 nm (0.75 – 3.0 µm)
  • MIR/MWIR (Medium/Mid-/Middle wave Infrared): 3.0 – 5.0 µm
  • LWIR/FIR (Long wave infrared/ Far infrared): 5.0 – 8.0 – 14.0 – 20.0 µm

Infrared coatings


Capabilities

3photon experienced team of quality assurance professionals can handle sensitive materials and our coating engineers and physicists can design and apply several types of infrared coatings:


 

 

Case studies – AR coatings on infrared (IR) crystals


TASK: Develop High LIDT coatings to increase efficiency of absorption and transmission bands of ZGP crystal


ZGP crystal (Zinc Germanium Phosphide) is widely used in infrared range, usually in imaging or defense applications. Very precise procedure is required to avoid contamination and produce ZGP crystals with maximal laser damage threshold. 3photon team designed and applied coatings where LIDT >2 J/cm2 @ 2.1 µm, 20 ns, 10 Hz, was not a limit.


 

 


TASK: Design complex AR coating solution on AgGaSe2 crystal for SWIR and FWIR


AGSe (AgGaSe2 or silver selenogallate) is widely used IR crystal and champion in three-wave interactions. It is used as an alternative to ZGP crystal, in infrared optical parametric oscillators (IR OPO), and harmonic generation. Our coating on AGSe crystal was designed to increase crystal’s overal performance.


 

 

Case studies – Coatings on infrared (IR) waveplates


TASK: Reduce reflection of infrared crystal surfaces in IR waveplate @ 7.0 – 9.5 μm


Infrared waveplates can be coated with anti-reflection coating to increase transmission by reducing light losses. 3photon engineers designed and deposited durable infrared coating on middle wave infrared waveplate made of infrared crystal.


 

 


TASK: Increase transmission of MgF2 IR waveplate @ 5.8-6.0 μm


Infrared waveplates made from MgF2 can also be easily AR coated to increase performance. Coating can be optimized for specific wavelength or broad range of infrared wavelengths.


 

Case studies – Infrared coatings on calcium fluoride


TASK: Produce broadband (BBHR) MWIR mirror for medical laser


This specific broad band infrared mirror coating is designed for low power applications. Coating was deposited with electron beam evaporation method. Due to porosity of the coating waterline can be observed around 2900 nm region, yet still, high reflection values at 2.9 μm can be achieved. To avoid waterlines, more dense coatings (e.g. Ion beam sputtering) should be used.


 

 


TASK: Filter out 1064 nm from MWIR


When very far infrared is not necessary – Calcium fluoride can be used as substrate for dichroic mirror. Our engineers designed and applied IR coating to filter out 1064 nm from middle wave infrared.


 

 

Case studies – Broadband AR coatings on Silicon (Si) and Germanium (Ge)


TASK: Increase transmission of Silicon (Si)  and Germanium (Ge) in MWIR (3000-5000 nm)


Wide-band AR coating 3000-5000 nm (3-5 μm) can be applied on Silica or Germanium windows to increase performance – decrease reflection per surface and maximizing overall transmission throughout whole element.

Anti-reflection coating on Silicon (Si) can be designed as per bellow curve:

A little bit better performance can be observed of anti-reflection coating on Germanium (Ge):

 

Case studies – IR coating on undoped and doped ZnSe and ZnS


TASK: Filter out 1310 nm or 785 nm from MWIR and FWIR


To filter out infrared spectra from specific wavelength, 3photon suggests infrared dichroic mirror coatings on zinc selenide (ZnSe) substrates.


 

 


TASK: Design universal dichroic coating on Fe:ZnSe and Fe:ZnS q-switch crystals to substitute IR optical components in laser cavity


3photon developed special coating design, which increases pumping efficiency. Furthermore, this coating can be applied on both Fe:ZnSe and Fe:ZnS crystals in one coating run.

 


 

 


TASK: Improve Cr:ZnSe crystal’s performance with anti-reflection coatings


Chromium doped Zinc Selenide (Cr:ZnSe) is used as laser crystal in MWIR lasers. 3photon IR BBAR coating on Cr:ZnSe reduces light losses on both crystal ends.

Photonics West 2020 – Overview

Photonics West 2020 is over!

 

Thank You for visiting us and for deep conversations about optical coatings, laser crystals, non-linear crystals, dielectric optics, metal optics and other laser components.

We are thankful for our client and co-exhibitor QS Lasers for pleasant company during the show!

Showcase and location

3photon  booth was located in transition hall D and thanks to new layout we were visited by unexpected amount of attendees from universities, institutes and industrial companies.  During Photonics West exhibition 3photon presented pockel cells, high LIDT LBO crystals, optics and components for temperature control.  Our optics showcase was full of laser crystals, such as  Cr:ZnSe, Nd;YAG, Alexandrite,  non-linear crystals AgGaSe2 (AGSe)AgGaS2 (AGS),  BBO,  and laser optics  ultra-resistant Silver mirrors, variable reflection mirrors, dichroic mirrors (output couplers) and other products, such as lenses and windows heaters.

 

Interest in key products

One of our key products high LIDT Lithium Triborate coated with multi-layer anti-reflective dielectric coating attracted a lot of attention. Special coating design allows us to produce very resistant coatings on LBO crystals.

Another product – mono-crystalline Chromium doped Zinc Selenide (Cr:ZnSe) We can supply this crystal in various quantities, dimensions and concentrations of chromium. Our customers use this crystals to construct middle infrared lasers and other optical devices.

For some of our visitors we have also presented custom Pockels cells. These cells are plug-and-play and extremely efficient! Our expertise in coatings on sensitive crystals allowed us to replace protective windows with protective anti-reflective coatings which drastically reduces light loss! Our clients enjoy custom sizing because they can easily use and fit the Pockels Cell where they desire.

 

Other activities

However, show wasn’t limited to exhibition, 3photon representatives  attended other activities organised by SPIE and EPIC.

As always, during welcome reception 3photon representatives met exhibitors and attendees in informal environment, this is great event to kick-off the exhibition!

Networking meetings with other EPIC members allows 3photon to always have up-to date information on market trends and meet people to share ideas and start new projects together. And, of course, EPIC CEO morning run – to stay in shape.

 

Our team is looking forward to meet You next year!
