Techwin laser diode DWTOSA with pigtail, designed for applications requiring stable wavelength control, integrate a Thermoelectric Cooler (TEC), a thermistor (NTC), and an isolator for precise temperature management and wavelength stability.
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 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 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.
