High Power Narrow Spectral Width: 780nm Broad Stripe DFB Laser Power Breaks Through 10W
2024.12.30
In today's rapid development of laser technology, high-power and narrow-spectrum lasers have become core requirements in many scientific and industrial fields. Recently, a research team led by Professor Wang Jun, CTO of Changguang Huaxin and from Sichuan University, achieved a major breakthrough with a 780nm wide-stripe distributed feedback (DFB) laser, achieving continuous output power exceeding 10W at room temperature. This research result was published in the authoritative photonics journal "IEEE Photonics Journal," demonstrating the team's significant progress in high-performance laser design.
20.2 mW! Single-mode VCSEL power efficiency sets a new record
2024.12.11
The research team led by Professor Wang Jun from the School of Electronic Information at Sichuan University and Suzhou Changguang Huaxin Optoelectronics Technology Co., Ltd. proposed a method to enhance single-mode VCSEL power by extending longitudinal gain based on multi-junction VCSELs. They also developed a mode analysis model for multi-junction VCSELs, solving the problem of single-mode power being difficult to exceed around 10 mW. This represents the highest single-mode power for a single VCSEL to date, with power nearly twice the current single-mode power record.
