ATLAS 1550 – C-band wavelength-tunable laser
A wavelength-tunable laser at 1550 nm, beyond the telecom C-band, is well-suited for telecom, as a lab tool for optical component testing and advanced photonics research, such as quantum key distribution (QKD). We offer two versions: the ATLAS1550-100, with a broad 100 nm tuning range, and the ATLAS1550-50, with a 50 nm tuning range, delivering slightly higher output power at a cost-effective price point.
ATLAS 1550-100 Specifications
| Parameter | Specified Values |
|---|---|
| Center wavelength | 1555 ± 5 nm |
| Wavelength range | 100 nm |
| Wavelength resolution | 10 pm |
| Wavelength accuracy | ± 10 pm |
| Wavelength switching time | 20 ms |
| Fiber output power at central wavelength | ≥ 10 dBm / 10 mW |
| Fiber output power at full range | ≥ 8 dBm / 6 mW |
| Intrinsic linewidth | ≤ 1 kHz |
