Improving the spectral performance of extended cavity diode lasers using laser chips with bent ridge waveguide
/en/research/research-news/improving-the-spectral-performance-of-extended-cavity-diode-lasers-using-laser-chips-with-bent-ridge-waveguide
Spectral purity is one of the key parameters of the performance of ECDLs. We present an approach to improve the side mode suppression of ECDLs by using semiconductor laser chips with an advanced…
