RWE Gain Chips
Product information "RWE Gain Chips"
655-1060 nm; Tuning Range 10-140 nm; Typ. Output Power (Extra Cavity) 15-80 mW; Forward Current 120-200 mA; Cavity Length 1000-2000 µm
Toptica eagleyard’s RWE series of gain chips are modified Fabry-Perot Laser Diodes with an excellent AR coated output facet. While not self-lasing, they are intended to be operated in external cavity setups (ECDL), such as in Littman or Littrow configuration. With external feedback they reveal narrow single frequency operation (a linewidth under 100 kHz is achievable) in combination with superior tuning capabilities over their entire gain width.
Within the RWE series, 760 nm gain chips are closing the wavelength gap between popular solutions around 780 nm, while 740 nm gain chips are reaching out 730 nm and below. The popular RWE gain chips at 760/840/1060 nm are additionally available in a widely tunable version. An improved chip structure enables a wider gain and thus broader tunability over 100 nm covering more interesting wavelengths in ECDL setups.
