CoBrite laser tuning principle

Each CoBrite laser variant offers two tuning modes: coarse and fine. In coarse tuning, users can access the full specified tuning range, while fine tuning enables precise frequency adjustment by offsetting the coarse tuning set point within a small range.

Coarse tuning mode description

This tuning mode enables laser frequency adjustment across the specified range for the laser port. During the tuning process, the output gets briefly disabled.

Tuning Process Description:

  1. Output is switched off.
  2. Output is re-activated using the new frequency.
  3. Power is gradually increased until the final output power is attained. Maximum tuning durations vary by laser type; consult the specifications for specifics.
  4. Power stabilizes, completing the tuning process.

Fine tuning principle

Fine tuning permits laser-detuning within a narrow range from the target frequency set by the coarse tuning parameter. During the tuning process, the laser will detune to the target setting with output power active, changing the output frequency in a linear ramp. Tuning resolution depends on the laser type; please refer to the specifications of the different laser types.

Tuning Process:

  1. Tuning is initiated.
  2. Tuning process speed depends on the laser type and takes approx. 0.5 to 10 seconds per GHz.
  3. Power remains constant throughout the process; laser settles on the new value.
