Ultrashort Pulse Fiber Laser: $4,600

You can purchase a 1.5 μm band ultrashort pulse fiber laser for less than $5,000 (tax-included).
Because all electric parts necessary for a 1.5 μm band ultrashort pulse 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 ultrashort pulse fiber laser as the research advances.
