Eletctonically-Tunable Laser

An intracavity defractive tunable filter which is driven by RF signal (Acousto-optic tunable filter: AOTF) is inserted into the laser cavity of tunable laser. Monochromatic laser comes from the laser cavity which constructed for the defracted emission selected by the AOTF. The laser has many advantages; stable, fast scan, quick access, and fluorescence free.

  • No mechanical movement of tuning element brings high stability.
  • The transition time between two wavelength depends on AOTF, it would be less than 1 us for any interval.
  • Easy rejection of background fluorescence (spontaneous emission) from laser medium.
  • PC, smartphone, and handset can be used to control wavelength.

Ti:sapphire

Applying 10 W CW laser at 532 nm as a pump laser to Ti:sapphire, typical specifications are as follows.

  • Maximum averaged power: 1 W (at~800 nm)
  • Wavelength range: 740~920 nm
  • Line width: <0.5 nm
  • Transition time: <1 us (between any two wavelength)

Other tunable laser

Other material can be applied. Below is few examples of material. Required pump laser and achievable specifications depend on laser medium.

  • Forsterite (Cr:Mg2SiO4): wavelength range 1180~1320 nm
  • Cr:ZnSe: wavelength range 2350~2950 nm
  • Yb fiber: wavelength range 1030~1100 nm
