1550 nm Pulsed Laser Diode

November 9, 2014

OSI Laser Diode, Inc. (LDI) (Edison, NJ) has introduced a 1550 nm pulsed laser diode with an integrated micro lens that delivers a far‑field beam pattern. The beam pattern's divergence is equivalent in both the Fast (perpendicular) and the Slow (parallel) axes of emission. The CVLL 350‑CL90 pulsed laser diode beam divergence (FWHM) is 8 x 8 degrees. The adjusted Far Field pattern offers high coupling efficiency when used with standard spherical lens systems. LDI's new device is RoHS compliant and operates in wavelengths ranging from 1530 nm to 1580 nm, with 1550 nm typical. The operating temperature is 25 degrees C, the pulse width is typically 150 nanoseconds, frequency is 5kHz, the drive current is at 75 W, and peak power is at 22 W.
