760 nm single-mode VCSEL for TDLAS Oxygen sensing
PrioLas' 760nm single-mode VCSEL are designed for oxygen sensing by Tunable Diode Laser Absorption Spectroscopy (TDLAS) and operate over a wide operating temperture range.
The typical wavelength can be chosen between 759 nm and 766nm @2.0mA, 20°C. The wavelength tolerance is specified at +/-1 nm.
Emitted output power versus laser current for chip temperatures ranging from 0°C to 80°C. For temperatures up to 80°C output powers above 300 µW are obtained for laser currents below 2 mA.
Wavelength versus laser current for chip temperatures ranging from 0°C to 80°C. The wavelength can be tuned over 4 nm.
Typical optical spectra of the 760 nm single-mode VCSEL over laser current and temperature range.
The VCSEL die (center chip) is attached on a Thermo Electrical Cooler (TEC) which is mounted on a TO39 header. The surface temperature is measured by a Thermistor (left chip). ESD protection is given by a Zenerdiode (right chip). The TEC enables a wide temperature tuning range. To reach 80°C only 150 mA@0.45V have to be applied.
760, 761, 763 and 764 nm single-mode VCSELs in TO39 w/ TEC and TO46 are available from stock.
