Note that the ultra-low-noise hybrid lasers are extremely sensitive to both seismic and acoustic vibrations, so a mounting fixture that dampens vibration is suggested. In the world of diode lasers, there are currently four main configurations to obtain a single-frequency output: external cavity laser (ECL), distributed feedback (DFB), volume holographic grating (VHG), and distributed Bragg reflector (DBR). This class of laser is safe under all conditions of normal use, including use with optical instruments for intrabeam viewing. These instruments have full remote control capability and can be addressed using serial commands sent from a PC. If the current is increased from 700 mA, the output will not become single mode until a current of approximately 715 mA (red curves on the graph below); however, after entering this region of single mode operation, the drive current can be lowered to almost 700 mA with the laser cavity maintaining single mode operation (blue curves). However, because the FBG temperature influences the supported lasing modes, the single mode regions shift. Optical EmissionThe optical output is a linearly polarized, free-space beam collimated by an integrated aspheric collimating lens, which is positioned in a tube located behind the shutter. The maximum supported edge transition time is 1 ms. The blue button in the Info column within the tables opens a pop-up window that contains more detailed specifications for each item, as well as mechanical drawings.
