Buying Frequency Tripling Devices
Frequency tripling is achieved through a combination of frequency doubling and sum frequency generation, typically resulting in ultraviolet light. These devices may include nonlinear crystals, mounts, ovens, optical resonators, and locking electronics to ensure efficient and stable wavelength conversion.
Making Good Purchase Decisions
As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.
NEW: Structured Decision Process
Purchasing involves a lot of responsibility. 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.

 Plauener Straße 163–165 / Haus N 13053 Berlin Germany See us at LASER World of Photonics 2025 in Munich, June 24–27 (booth B2.410) and CLEO 2025 in Long Beach (CA), USA, May 4–9 (Kiosk 731)! |  As part of our HarmoniXX product line, the HarmoniXX THG is a frequency converter for tripling the frequency of ultra short-pulse lasers. Unlike conventional triplers, the HarmoniXX THG requires less adjustment efforts, because no separation and recombination of the interacting beams is needed. This user-friendly feature has one common optical beam path for all interacting beams. It is implemented by means of a proprietary delay compensator and provides consistent spatial overlap for optimum efficiency. For more details, see our specifications. Product-specific web page |
 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)! |  Shalom EO offers a vast selection of nonlinear optical crystals for frequency tripling, also known as third harmonic generation (3 HG). Shalom EO supplies different kinds of NLO crystals including BBO crystals, CLBO crystals, KDP and KD*P, KTA, PPLN waveguides, LBO, KTP, HGTR KTP, BIBO, LiNbO3 and MgO:LiNbO3 crystals, YCOB, in addition to the infrared nonlinear crystals ZnGeP2 (ZGP) and LiIO3. Miscellaneous coating options including uncoated, AR, HR, HT, PR coatings, electrodes, and custom coatings are available. Both off-the-shelf and customized products are available. The crystals can be offered in the form of ingots, blanks, and laser-grade polished elements. Recent days, Shalom EO launched CLBO (cesium lithium borate) crystals. Processed and polished in low humidity workshop, our CLBO crystals feature excellent performance in UV, vacuum UV (VUV), and deep UV (DUV) wavelength ranges. Ultra-thin nonlinear crystals for femto-line lasers are also available. Product-specific web page |
 Your trusted value co-creation partner HC Photonics Corp.F4, No. 2, Technology Rd.
