Mode Locked Er Fiber Laser Kit (Wavelength 1.5 μm)

Ultrafast Fiber Laser: US$ 4,600

You can purchase a 1.5 μm band ultrafast fiber laser for less than US$ 5,000 (tax-included). Because all electric parts necessary for a 1.5 μm band ultrafast fiber laser are included in this kit, saving the bothersome work to select suitable optical parts, You will be able to easily accumulate laser light source developing knowhow while you mount the Kit by yourself.
Furthermore, thanks to higher degree of freedom d due to kit, you can easily rearrange the structure of 1.5 μm band ultrafast fiber laser as the research advances.
