• Operating Mode: Continuous

Ortel’s 1995 cooled TOSA laser module is characterized for use as a CW coherent optical source laser for LiDAR technology. The 1995 is DC-coupled with a built-in TEC, thermistor, and monitor photodiode. The device is in hermetic TO56 package with 6+1 pins. The 1995 incorporates a high-efficiency coupling scheme to deliver 15 dBm of CW optical power.

Ortel’s design provides a compact, robust solution for Frequency Modulation Continuous Wavelength (FMCW) sensing for autonomous vehicles and wide variety of other optical sensing applications. It is highly immune to mode or optical frequency hopping typically found with single isolator, external cavity designs. Mode or optical frequency hopping causes false readings in FMCW LiDAR, whereas Ortel’s laser technology maintains optical frequency stability over temperature suppressing false readings.
