The FEBP series 689 nm discrete mode laser diode is a coherent laser source with a 4 MHz linewidth and 2.5 mW optical output power (typical). Used for gas sensing and in strontium-based atomic clocks, a strained multi-quantum well discrete mode (DM) laser diode chip is packaged in a hermetically sealed TO39 can with an integrated TEC and thermistor.
