- CW operation refers to an operating mode in which the diode is left on continuously for extended periods of time, typically 20 minutes or more at a time.
- QCW (quasi-continuous wave) operation refers to a high repetition rate, short-pulse mode of operation (e.g., 200 µs pulses, 1 kHz). QCW products listed here are rated up to 20% duty cycle and pulses <1 ms long.
- Hard-pulsed operation refers to an operation mode in which the diode is repeatedly turned on and off – full current to zero current – with pulses longer than several milliseconds (e.g., 1 second on/1 second off operation).
- Please consult the factory for any requirements not listed here, including the following options which are available on a case by case basis: - Other bar geometries (emitter width, number of emitters) - Other wavelengths and spectral specifications. - Higher or lower operating powers. - Higher and/or lower operating temperatures. - Higher and/or lower storage temperatures. - Lensing options.. - Low smile options. Operating Notes
- Unit requires an adequate heat sink. Failure to supply an adequate heat sink will destroy the unit.
- Indium foil should be used between base of diode and heatsink to ensure good thermal contact.
- Mounting torque 8 in.-lbs. (with Indium foil).
- ESD precautions must be taken when handling unit.
- Negative current transients greater than 25 µA and/or reverse voltages >3V can destroy the unit.
- A dry environment should be provided when storing or operating a device with an open diode laser facet at temperatures below the ambient dew point. Failure to do so will cause condensation on the unit and can destroy it.
- Output powers in excess of specification will accelerate device aging.
- Operation at higher temperatures will accelerate device aging, increase threshold current, and lower slope efficiency.
- Care should be taken to avoid back-reflections into the device. Failure to do so can destroy the unit.
