The researchers list the advantages of their source over other existing blue sources as: 1. Fixed wavelength input pump source 2. Wide tuning range (425 nm - 489 nm) 3. High output power (up to 450 mW so far) 4. Single-frequency operation (<10 MHz linewidth) 5. Simple, compact, solid-state design.(Image credit: Goutam Samanta) |
