We all know that QSI laser diodes have a relatively large market share in China, but many people are curious about the advantages of QSI laser diodes? What is the market share of semiconductor lasers in China?

1、 The advantages of QSI laser diodes

According to publicly available information, QSI laser diodes have significant advantages in the following areas:

High photoelectric quality and low driving current

QSI provides 635-905 nm single-mode laser diodes with high optical and electrical quality in the short wavelength range. They have a small threshold current and low operating current, high efficiency, and stable performance.

High reliability and competitive pricing

The product is considered to have high reliability and competitive pricing within the industry.

Multi wavelength coverage and rich power specifications

The product range covers 635-940 nm and can provide red and near-infrared (IR) lasers with output power ranging from 5 mW to up to 750 mW in the IR range, meeting various application needs.

Compact packaging

We offer classic TO packages such as TO-18 and TO-5, and some models are equipped with built-in monitoring photodiodes (PD) for easy feedback control and power stability.

Widely applicable in various fields such as industry, military, 3D motion recognition, positioning measurement, scanning, laser pointers, barcode scanning, and optical modules.

In summary, QSI laser diodes have significant competitive advantages in terms of "high quality, low power consumption, high reliability, wide wavelength coverage, and rich packaging".

2、 Market share of domestic semiconductor lasers

A. Overall market situation of Chinese lasers

In 2022, the market size of China's laser industry has reached 87.6 billion yuan, accounting for over 50% of the global laser market share.

According to the distribution of laser types: fiber lasers account for about 53%, semiconductor lasers account for about 16%, and gas and solid-state lasers account for about 16% and 15%, respectively.

Based on this calculation, the market size of Chinese semiconductor lasers in 2022 is estimated to be approximately 14 billion yuan

B. Growth Trends and Main Driving Factors

Since 2019, the Chinese semiconductor laser market has continued to grow: reaching 4.84 billion yuan in 2022, and is expected to increase to approximately 5.5 billion yuan in 2023.

The market growth rate comes from the strong demand for high-performance laser devices in cutting-edge technology industries such as communication (especially 5G), autonomous driving, and intelligent manufacturing.

C. Comparison of Global and Chinese Laser Markets as a Whole

Although semiconductor lasers account for less than half of optical devices in China, there is significant room for improvement and they are in a rapid development stage.

The rapid growth of China's overall laser market (87.6 billion yuan) and the increasing proportion of semiconductor lasers year by year demonstrate its growing importance in the field of optoelectronics.
