Buying Q Switches
Q switches are devices used to produce short, intense pulses from lasers by modulating the intracavity losses. Common types include acousto-optic and electro-optic modulators, as well as semiconductor saturable absorber mirrors (SESAMs). They are essential in applications requiring high peak power and precise pulse control.
Making Good Purchase Decisions
RP Photonics helps you to not only to find all relevant suppliers, but also to make good purchasing decisions.
NEW: Structured Decision Process
We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.
(Various further improvements of this feature will come soon.)

![]() Kauhakorvenkatu 53B 33710 Tampere Finland | ![]() Our customized semiconductor saturable absorber mirrors (SESAMs) can be used as passive Q-switches in applications where short (max. few nanoseconds), high repetition rate and relatively low-energy pulses are required. Contact us for the optimal customized SESAM for your application. |
![]() Your problem is our challenge – flexibility is our standard! Artifex Engineering GmbH & Co KGDortmunder Str. 16–18 26723 Emden Germany | ![]() Artifex Engineering offers customised Pockels cells, available as DKDP (KD*P), MgO:LiNbO₃ and BBO. Our Pockels cells feature low insertion loss, high damage threshold. These are cost effective units at OEM prices. We also offer a range of standard Pockels cells with an aperture of 6 mm to 12 mm diameter. Visit our product page for more information. We look forward to your inquiry. |
![]() A635, Boke Mansion No. 9 Xiyuan Road Xihu District, Hangzhou 310030 China | ![]() Hangzhou Shalom EO offers standard and custom Q switches made of DKDP, BBO crystals and LiNbO3 or MgO:LiNbO3 crystals. Shalom EO’s DKDP Pockels cells feature high deuteration (>98%), low capacitance and fast rise time, and high transmission, high extinction ratio, with a maximum aperture of 50 mm. Shalom EO’s 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 high damage threshold, low insertion loss, high extinction ratio, minimal piezoelectric ringing, and competitive price. BBO Pockels cells with both Single and double BBO crystal designs and low-voltage geometries are available upon request. Hangzhou Shalom EO also offers polished and AR-coated DKDP, BBO and LiNbO3 and MgO:LiNbO3 crystals with Cr–Au electrodes which can be used as central components of Pockels cells. |
![]() C506, #1 Building Pioneering Park for Overseas Chinese Scholars No. 69 Huayang Road Lixia District Jinan, Shandong China | ![]() Laserton offers electro-optic Q switches based on KTP, RTP, BBO or KD*P Pockels cells. We also make devices with a thermally compensated double crystal design. Besides, Laserton offers Er:Yb:glass gain chips with integrated passive Q switches (saturable absorbers). |
![]() Your reliable partner for photonics innovations! EKSMA Optics, UABDvarcioniu St. 2B LT-10233 Vilnius Lithuania | ![]() We produce KTP, KD*P and BBO Pockels cells for high repetition rate Q-switching. Our Pockels cells can be supplied with mounting stages, drivers and power supplies. |
![]() Lasers, Optics, Electronics. Made in Germany. ALPHALAS GmbHBertha-von-Suttner-Str. 5 37085 Göttingen Germany | ![]() 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. |
![]() Nonlinear crystals pioneers Raicol Crystals Ltd.22 Hamelacha Str. Park Cibel, New Industrial Area Rosh Ha'ain 48091 Israel | ![]() 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:
