Product Overview:

These DBR laser diodes from eagleyard photonics are offered in a hermetically sealed butterfly package housing. This device offers up to 10mW of optical power. The data sheet references replacement of HeNe lasers as a primary application. These 633nm devices offer monitor photo-diode, thermoelectric cooler and thermistor as well as a collimated output beam. Key specifications from the attached data sheet include a center wavelength of 633.0 (+/-1nm) and a typical spectral width, full width half maximum, of 1 MHz. The temperature tuning coefficient for these laser is 0.045nm per degree Kelvin, and the current tuning coefficient is 0.001nm per mA of forward bias drive current. These devices offer a high side mode suppression ratio of > 30 dB and typically deliver a 90% degree of polarization. The technology is based on a distributed Bragg reflector. The reflector (Bragg mirror) is located external to the gallium arsenide based active area. Eagleyard Photonics DBR lasers have resistors which are integrated in order to facilitate mode-hop free tunability. Eagleyard offers the widest range of DBR lasers on the market. Wavelengths from 633nm through 1083nm are available.
