External-Cavity Semiconductor Laser ECL801
The ECL801 Littrow external-cavity semiconductor laser uses grating dispersion to feed a narrow spectral portion of the gain emission back into the laser diode, increasing mode competition and favoring single-longitudinal-mode, narrow-linewidth operation. The diode emission forms the output through the blazed grating's "0" diffraction order, while the "1" order returns to the diode to select frequency (Figure 1). The simple Littrow structure is easy to use. Current feedforward extends continuous wavelength tuning (Figure 3). For frequency stabilization, the ECL801 offers both current and PZT modulation to meet different user requirements.
