由Coherent 與 IPG 年報來看全球雷射發展新趨勢

2024 年雷射市場的驚奇之一，可能是Coherent( 相干公司) 股價創下了歷史新高，每股達到創紀錄 的109 美元( 約3500 元台幣)。曾經因董事會尋求經營轉機，面臨向全球兜售公司的Coherent，股價曾在2021 年來到每股24 美元的低點。在與II-VI 公司合併後，短短的3 年間，市值成長了4.5 倍。2021 年如果投資100 萬的Coherent，如今將可達到450 萬。Coherent 是如何反敗為勝的呢? 相當值得我們深究。反觀2010 年到2020 年雷射產業最紅的 IPG photonics( 阿帕奇雷射)，股價在2021 年達到每股252 美元的最高價後，一路崩跌到目前的每股78 美元，股價崩跌了70%。2021 年如果投資100 萬的IPG，如今只剩下31 萬。如果說股票是經濟與技術的櫥窗，這兩間公司的營運變化，肯定代表著某一種雷射技術的變遷。本文將以Coherent 與 IPG 的年報，嘗試分析背後所代表的雷射發展趨勢，並整理兩家公司未來尋求精進的發展方向。

One of the surprises in the laser market in 2024 may be that Coherent's stock price reached a historical high, hitting a record $109 per share (about 3,500 New Taiwan dollars). Coherent, which seeking a business turnaround from its board and was on the verge of selling itself globally, saw its stock price drop to a low of $24 per share in 2021. After merging with II-VI, its market value grew 4.5 times in just three years. An investment of $1 million in Coherent in 2021 would now be worth $4.5 million. How did Coherent turn things around? This is certainly worth exploring. In contrast, from 2010 to 2020, the most popular company in the laser industry, IPG Photonics, saw its stock price peak at $252 per share in 2021, only to plummet to $78 per share now, a decline of 70%. An investment of $1 million in IPG in 2021 is now worth only $310,000. If stocks are a showcase of the economy and technology, the operational changes in these two companies undoubtedly represent a shift in laser technology. This article will attempt to analyze the trends in laser development represented by the annual reports of Coherent and IPG and summarize the future development directions both companies are seeking to improve. these key players, aiming to provide insights for Taiwanese companies seeking to enter this transformative market.
