Purchasing Advisor for Q Switches
Find all you need for professionally buying Q switches: an interactive tool with a comprehensive and trustworthy directory of suppliers and expert guidance for a structured decision process with scientific and technical background information.
Top-level product category: various devices
More specific product categories: acousto-optic Q switches, electro-optic Q switches, saturable absorbers, semiconductor saturable absorber mirrors
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.

![]() A635, Boke Mansion No. 9 Xiyuan Road Xihu District, Hangzhou 310030 China See us at LASER World of Photonics 2025 in Munich, June 24–27 (hall B1, booth 258)! | ![]() 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.

![]() 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. Product-specific web page |
