The FPD (NP) series are multiple longitudinal mode, CW Fabry-Perot laser diodes with average output powers of up to 35mW. Custom wavelengths are available from 750nm to 3,000nm. Some wavelength tuning is achievable through temperature control, but the rate of tuning with temperature and the tuning range are not specified.
These laser diodes come in a wide range of standard laser diode packages:
- TO5.6mm and TO9mm headers with or without cap. These require an external TEC to cool the diode, and to temperature tune for coarse wavelength tuning.
- TO5 style packages are complete with built in TEC and thermistor.
- 14 pin butterfly package (complete with TEC and thermistor).
A monitor photodiode built into the laser diode package allows measurement of the output power. It also achieves a higher degree of output power stabilisation, when used with the appropriate drive electronics. Drive electronics are not included. Laser 2000 supplies a range of suitable drive drivers and temperature controllers. Please see the laser accessories section. Optional windows and lenses can be fitted; both BK7 and sapphire caps are available.
With a long lifetime and highly repeatable performance, these devices meet the demands of laboratory based applications and OEM applications alike. They are reliable in harsh and demanding environments.
