Techwin 785/830/1064nm Butterfly Laser Diode designed specifically for Raman spectroscopy detection. Techwin 785/830/1064nm Butterfly Laser Diode utilizes Volume Bragg Grating (VBG) stabilization. This ensures excellent wavelength stability, narrow spectral linewidth, and high side-mode suppression ratio (SMSR) even at high power output levels.
The laser diode is housed in a standard 14-PIN butterfly package and is available with either 105/125 multimode fiber coupled output with an FC/PC connector or free space beam output, offering good compatibility. This series of products is widely used in Raman detection, optical sensing, and other related fields.
Techwin 1550nm DFB laser diode is designed for LiDAR applications, featuring single longitudinal mode and high power output. The laser is housed in a standard 14-PIN butterfly package with a standard polarization-maintaining (PM) fiber and FC/APC connector output, ensuring good compatibility. This series of products is widely used in LiDAR, fiber optic sensing, and other related fields.
Techwin 1653.7nm butterfly laser diode is specifically designed for methane (CH₄) gas detection, featuring high power, stable wavelength, narrow spectral linewidth, and a high side-mode suppression ratio (SMSR). The laser is housed in a standard 14-PIN butterfly package with standard single-mode fiber and an FC/APC connector output, ensuring good compatibility. This series of products is widely used in optical sensing and gas detection. We can also customize different wavelength gas detection sensors according to customer requirements.
Techwin's 1550nm Narrow Linewidth Laser Diode is designed for ultra-narrow linewidth applications, utilizing Volume Bragg Grating (VBG) stabilization. This ensures high power, low noise, and a narrow linewidth, with a minimum linewidth achievable below 3kHz.
The laser is housed in a standard 14-PIN butterfly package and is available with single-mode or polarization-maintaining (PM) fiber, featuring an FC/APC connector output for good compatibility. This series of products is widely used in fiber optic sensing, laser radar, and other related fields.
Techwin TO-Can Laser Diode integrated with advanced packaging technology, can incorporate a thermoelectric cooler (TEC) and a negative temperature coefficient (NTC) thermistor. The TEC enables high-precision temperature control, resulting in lasers with high power and stable wavelength. We also offer heated TO packages suitable for operation in the -10°C to 50°C range. These lasers feature collimated light output.
