Gain chip for 990-1140nm tuning range, 200mW @ 1060nm, QGC-1060-150-200
Online price:
    • Designed for external cavity tunable laser
    • Optimized for wavelength locked operation
    • High Signal / ASE ratio


    Gain chip has curved stripe with HR-coating on the back facet and deep AR-coating on the tilted front side.  The curved stripe along with deep AR-coating provide extremely low reflection (< 10E-5) resulting in suppression of self lasing and minimizing of gain ripples.

Additional information

The laser light emitted from this device is invisible and can be dangerous to the human eye. Avoid looking directly into the fiber output or into the collimated beam along its optical axis when the device is in operation. Proper laser safety eyewear must be worn during operation.

Absolute Maximum Ratings may be applied to the device for short period of time only. Exposure to maximum ratings for extended period of time or exposure above one or more max ratings may cause damage or affect the reliability of the device. Operating the product outside of its maximum ratings may cause device failure or a safety hazard.

Power supplies used with the device must be employed such that the maximum peak optical power cannot be exceeded. A proper heatsink for the device on thermal radiator is required, sufficient heat dissipation and thermal conductance to the heatsink must be ensured. The device is an open-heatsink laser diode; it may be operated in cleanroom atmosphere or dust-protected housing only. Operating temperature and relative humidity must be controlled to avoid water condensation on the laser facets. Any contamination or contact of the laser facet must be avoided.

ESD PROTECTION – Electrostatic discharge is the primary cause of unexpected product failure. Take extreme precaution to prevent ESD. Use wrist straps, grounded work surfaces and rigorous antistatic techniques when handling the product.
