RTP: The Optics Material of Choice for the Advanced LIGO (June,16,2019)

The Advanced LIGO ushered in a new era of science – using higher sensitivities than the initial LIGO, for direct observation of gravitational waves for the first time. As part of the upgrade, the laser power of the system was greatly increased, leaving its existing LiNbO3 modulators ineffective. Raicol’s RTP Q-Switch was chosen as a replacement.

ESA-JAXA BepiColombo mission to Mercury (November,29,2018)

We are pleased to announce that at 01:56:28 GMT on October 20, the ESA-JAXA BepiColombo mission to Mercury blasted off on an Ariane 5 from Europe’s Spaceport in Kourou, French Guiana in South America. Ariane 5 carries on board the BepiColombo Laser Altimeter (BELA) in which Raicol ‘s crystals have been used to build a space-qualified Q-Switch for the laser range finder. After a 6-year cruise, the BepiColombo Laser Altimeter will start recording topographic data from orbital altitudes between 400 and 1500 km above Mercury’s surface. This is a joint mission between Europe and Japan. Many actors were involved in the design, construction, and launch of the satellite. Hensoldt Optronics was prime-contractor for the “BELA Laser” for which the Q-Switch was selected.

Raicol Crystals is the leading pioneer in the manufacturing of RTP EO Cells. 
Our RTP crystals are primarily utilized in laser systems for airborne and space applications  (Apr, 08, 2018)

RTP products

RTP crystals are featured in Q switches, pulse pickers, phase modulators, amplitude modulators and cavity dumpers.

Due to the unique advantages of our RTP crystals over standard LiNbO3 crystals, they have become the crystal of choice for airborne and space laser systems worldwide.

Advantages of Raicol’s RTP Crystals:

  • Wide temperature range (-50°C to 70°C)
  • Compact design due to low half wave voltage
  • No dynamic HWV component
  • No pyroelectric & elasto-optic effects
  • High damage threshold (600MW/cm2, in most cases 1GW/cm2)
  • A high extinction ratio of up to 30-35dB
  • No acoustic ringing
  • Wide acceptance angle
  • Non-hygroscopic material
  • Low electrical conductivity (rise time/fall time 1ns)

Super Polished LBO Crystal (Dec. 11 , 2017)

If you are using Second and third harmonic generation of high power diode pumped
solid-state lasers you should try our Super Polished LBO!

Why should you buy Raicol’s LBO?

  • We are the only one in the world who achieved a result of RMS in roughness measurements, which makes our LBO a super polished element with excellent surface quality with 2/1 scratch and digs.
  •  Our LBO has a very low bulk absorption: up to 2ppm/cm at 1064nm which makes our absorption amongst the lowest value available over the market place.
  •  We can offer large size of LBO elements up to 50×50 mm 2 and maximum length of 40 mm.
