Near-infrared TDLAS (sulfur dioxide) C2H2 ppb level concentration analysis system TDLAS-1520-C2H2-NIR

TDLAS (Tunable Diode Laser Absorption Spectroscopy) is a new gas detection method developed on the basis of combining diode laser with long optical path absorption cell by modulating the wavelength of laser through the characteristic absorption area of the gas to be measured. The spectrum of the semiconductor laser light source used in TDLAS technology is much smaller than the broadening of the gas absorption spectrum, and a single-line absorption spectrum is obtained. Therefore, TDLAS technology is a high-resolution absorption spectrum technology. Acetylene: C2H2, commonly known as wind coal or carbide gas, is the smallest member of the alkyne compounds and is mainly used for industrial purposes, especially in welding metals. Acetylene is a colorless, highly flammable gas at room temperature. Pure acetylene is odorless, but industrial acetylene has a garlic smell due to impurities such as hydrogen sulfide and phosphine.

440nm 1x2 High Power Large Core Multimode Fiber Coupler

VIS-MFC -LMA series large core fiber couplers are developed and produced based on our fiber fusion taper machine IPCS-5000-LMA. They are used for visible light band splitting. They have excellent performance. Unlike multimode fibers (50/125, 62.5/125) widely used in fiber optic communication systems, large core fibers are usually used to transmit larger laser powers and special working bands. At the same time, due to the large core diameter and high numerical aperture of the fiber, the uniformity and stability of large core fiber splitting are affected by many factors (such as laser mode, laser injection method, etc.). With the accumulation of many years of high-energy laser transmission experimental foundation and the research on the reliability of military devices, we can provide fiber splitters with core diameters of 125um to 1500um, as well as large core fiber splitters working at all wavelengths. The products have extremely high resistance to high-power laser shock and high environmental reliability. Since its establishment, the company has continuously invested in research and development to optimize and improve the melting process of special large core fiber splitters and product packaging processes. We have made breakthroughs in product miniaturization, multi-core optical fiber one-time melting molding, laser mode sensitivity removal, etc. We have provided large-core optical fiber splitter products exclusively to many domestic and foreign customers.

Near infrared TDLAS NH3 (ammonia) ppm level concentration analysis system (1512nm)

TDLAS (Tunable Diode Laser Absorption Spectroscopy) is a new gas detection method developed based on the combination of diode laser and long optical path absorption cell by using laser wavelength modulation to pass through the characteristic absorption area of the gas to be measured. The spectrum of the semiconductor laser light source used in TDLAS technology is much smaller than the broadening of the gas absorption spectrum, and a single-line absorption spectrum is obtained. Therefore, TDLAS technology is a high-resolution absorption spectrum technology. Ammonia: NH3 is a colorless gas with a strong irritating odor, which is lighter than air. This gas usually comes from concrete admixtures used in construction and additives and brighteners in interior decoration materials. Long-term exposure to ammonia will burn the skin, eyes, and respiratory mucosa. If people inhale too much ammonia, it can cause lung swelling and even death.

1567nm VCSEL Vertical Cavity Surface Emitting Laser 1.0mW PL-VCSEL-1567-1-A81

Vertical-Cavity Surface-Emitting Laser (VCSEL) is a semiconductor laser that emits laser light perpendicular to the top surface. It is developed based on gallium arsenide semiconductor materials, which is different from LED (light emitting diode) and LD (laser diode). The structure consists of a mirror, an active layer and a metal contact layer. The two emitting mirrors are P-type and N-type Bragg emitters respectively. The active region is composed of quantum hydrazine, and a metal contact layer is made on the outer surface of the P-type DBR to form an ohmic contact, and a circular outlet is made on the P-type DBR to output the laser. It has a small far-field divergence angle, and the divergence angle beam is narrow and round; and the threshold current is low and the modulation frequency is high, which can reach 300KHz. Wavelength tuning can be achieved by changing the laser current and temperature. It is designed for high-speed fiber optic communication with built-in TEC and PD packaging.

Wavelength-locked FBG (Fiber Bragg Grating)

Fiber Bragg Gratings have many applications in optical communications, laser technology and sensing systems. FBGs are widely used as fiber reflectors or optical filters with narrowband spectra. FBGs can be used as sensitive elements for strain and temperature measurements.Wavelength Locker FBGs are used as external reflectors for laser diodes. The wavelength generation of pump semiconductor lasers and single frequency lasers is easily stabilized using such fiber gratings. Low reflection gratings with FWHM 0.3 nm – 0.8 nm and reflectivity 2% – 5 % are ideal for pump power laser stabilization. FBGs close to semiconductor laser crystals with FWHM of about 0.1 nm and reflectivity of 10% - 20% are used to create single frequency sources. We present a family of WL FBGs with different accurate wavelength positions up to ± 0.02 nm. The transmission spectrum of the wavelength locked FBGs for laser diode power and wavelength stabilization is shown in the figure.
