Since the advent of the first solid-state pulsed ruby laser, the development of lasers has been very rapid, and lasers with various working materials and operating modes have continued to appear. Lasers are classified in various ways:
The xiamen optical Exhibition China 2023, XMIPE was successfully opened on November 13th. The products exhibited by BoxOptronics include 840nm SLD broadband light source, DFB butterfly laser and erbium-doped fiber amplifier.

Narrow linewidth lasers are widely used as light sources and receivers in fiber optic communication systems. In terms of light sources, narrow linewidth lasers can provide high-quality and highly stable optical signals, which can reduce signal distortion and bit error rates. In terms of receivers, narrow linewidth lasers can provide high sensitivity and high-precision light detection, which can enhance the signal detection capabilities of the receiver. In addition, narrow linewidth lasers can be used for functions such as optical filtering and frequency conversion.
Single-frequency fiber lasers have a very narrow limit linewidth, and their spectral line shape is Lorentz type, which is significantly different from single-frequency semiconductors. The reason is that single-frequency fiber lasers have longer laser resonant cavities and longer photon lifetimes in the cavity. This means that single-frequency fiber lasers have lower phase noise and frequency noise than single-frequency semiconductor lasers.
At the 2023 Indo-Pacific International Maritime Exhibition, Australian Optronic Systems demonstrated its newly developed anti-drone soft-kill solution for the first time.
