Shalom EO offers Pockels cells made from DKDP, BBO crystals and LiNbO3 or MgO:LiNbO3 crystals:

  • Our DKDP Pockels cells have a high damage threshold and can be used in a wide spectral range from 0.3 to 1.1 μm; it is often used in medical, cosmetic and industrial lasers. Apertures up to 50 mm are available.
  • Our LiNbO3 and MgO:LiNbO3 Pockels cells are excellent choices for ultraviolet (UV) lasers to infrared lasers with long operating wavelengths up to 4 μm. LiNbO3 Pockels cells are specially preferable for Er:YAG, Ho:YAG and Tm:YAG lasers.
  • Our BBO Pockels cells have significant advantages in terms of laser power handling abilities, temperature stability, and substantial freedom from piezoelectric ringing. BBO Pockels cells are specially suitable for high repetition rate lasers up to 1 MHz.

Hangzhou Shalom EO also offers polished and AR-coated DKDP, BBO and LiNbO3 and MgO:LiNbO3 crystals with Cr-Au electrodes used in EO and AO Pockels cells.

Q switches

ALPHALAS offers a combination of high-speed, high voltage Pockels cell drivers with a Pockels cell for active Q-switching, designed for all standard laser wavelengths. Rise times below 1 ns and amplitudes > 10 kV cover even the most demanding applications. Repetition rate can be as high as 100 kHz.

The acousto-optic Q-switches from ALPHALAS have the advantage to operate in the MHz repetition rate range where the electro-optical Q-switches can operate only at the cost of considerable technical efforts and complex water-cooled design.

The passive Q-switch alternative has the advantage of simplicity, durability and low cost when compared with the active Q-switching alternative. Cr4+:YAG, V3+:YAG and Co-spinel (Co2+:MgAl2O4) cover the spectral range from 900 nm to 1600 nm. Most Q-switching crystals are available from stock.

Q switches

Raicol Crystals offers a wide range of electro-optic solutions, including RTP, BBO, i-RTP, and LN, catering to diverse electro-optic applications. Some of those are particularly suited for Q switching of lasers:

  • RTP (rubidium titanyl phosphate) is an excellent choice for electro-optic applications, such as Pockels cells, shutters, Q-switches, phase modulators, pulse pickers, and more. The outstanding electro-optical parameters enable extremely fast switching with rise/fall times under 1 nanosecond and high repetition rates exceeding 1 MHz, all without ringing.
  • BBO (beta barium borate) crystals combine a wide transparency range, high damage threshold, and excellent chemical and mechanical properties, making them ideal for various electro-optic applications.
