Hello, thank you for contacting Thorlabs. Dear rodolfls, I apologize for the delay in getting this information to you. When the blade sweeps through the angle θ , the rise or fall time of the S-curve is proportional to the size of the beam along the direction of the blade's travel (Figure 5). We have fiber polarization management solutions in the link below. Diodes are arranged by wavelength and then power. I want to know some information about LASER DIODE COMBI CONTROLLER:ITC510,would you do me some help? However, for a current of 65 mA with a slope efficiency of .75 it would produce an output power of 48.8mW not 22.5 mW as stated. Is it possible to let us know the coating material on the output facet of these diodes? Aroop Kanti Bose Example: S-Curve with Rising EdgeThe angle (θ = ftr ) subtended by the beam depends on the signal's rise time (Figure 6) and the wheel's rotation rate (f ), whose units are Hz or revolutions/s. Laser diodes in their original sealed package can be returned for a full refund or credit. But selling a DL3146-151 for 1418€ doesn't seem to be a fair price at all, since exactly the same product is being sold for only 18€, for example if you check: http://www.roithner-laser.com/pricelist.pdf. While the diode can in theory be pulsed, we recommend applying a DC bias current to threshold and pulsing above that. The 1418 Euro price is based on what it cost Thorlabs to purchase the laser diodes in 2008. A;chopper wheel, photodetector, and oscilloscope can provide an approximate measurement of the beam size (Figure 4). After clicking "Choose Item" below, a list will appear that contains the dominant wavelength, output power, and operating current of each in-stock unit. The new page will go live shortly. Always mount the laser in a suitable heat sink to remove excess heat from the laser package.
