"Core" Yaoguang Expo | DoGain technology report + new product release, highlights continue
On March 19, the core of the Dogain was inShanghai Munich Light Expo Booth N5.5308, brought four wonderful special technical report sharing, aroundSemiconductor laser chips, single-mode devices, 10,000-watt light sources, and low-temperature drift pump modulesThe four major product technology directions showcased the company's latest innovative technological achievements and industrialization development, attracting many industry experts, industrial chain partners and customers to stop and consult.
Light blades break the boundaries and create the future intelligently
High-efficiency and reliable semiconductor laser chips
Relying on the IDM full-chain industrial system, Dogain has overcome a number of technical barriers and formed a full range of high-performance, high-reliability single-mode, multi-mode, and array laser chip products.
A new generation of high-efficiency 915/976nm 45/55/66W single-tube chips
Electro-optical conversion efficiency increased from 65% to 67~68%, high temperature control stability, effectively reduce the energy consumption and heat dissipation pressure of the fiber laser pump source.
High-power 976nm 35W DFB chip
The peak power is over 45W, which is the highest power for commercial public use,Full current range wavelength lock ± 2nm, eliminating the complex external cavity wave locking scheme, helping the large-scale implementation of highly stable pump sources.
A new generation of 915nm/975nm 65W single-tube chips
400μm strip width + 6.5mm cavity length design,The power is increased by 10W compared to the previous generation, the slow axis divergence angle remains unchanged,Lateral brightness up to 3.7W/(mm·mrad), taking into account both high power and high brightness.
808nm 800mW single-mode chip
Breaking through the highest single-mode reliable power in the 808nm band, it is suitable for high-end scientific research and precision equipment development scenarios.
808nm 6-22W multimode chip
808nm 10W multimode chipPassed 7000 hours of high-temperature aging verification, solve the pain points of the short-wavelength chip power degradation industry and build long-term operational reliability.
Single-mode light precise empowerment
High-performance single-mode semiconductor laser chips and devices
Focusing on single-mode laser devices, the core of Dogain has been successfully developed14PIN、10PIN、3PINSingle-mode high-power module products in a variety of package series, wavelength coverage830、905、980、1030、1064、1080nmand other bands, building a complete single-mode product line and passing rigorous Telcordia reliability tests.
