193nm-5000nmNarrow linewidth laser with arbitrary wavelength (laser selection based on wavelength) 3432nm Narrow Linewidth Lasers

3432nm Narrow Linewidth Lasers

The frequency accurate laser uses an ultra narrow linewidth fiber DFB laser as the seed source, and uses an all fiber amplifier for power amplification. The scheme of two fundamental frequency beams passing through a nonlinear crystal in a single pass can achieve narrow linewidth and high power 3432nm laser.
