Abstract: A mid-infrared broadband laser including: a femtosecond laser configured to generate a near-infrared light; nonlinear waveguide configured to broaden and/or shift a spectrum of the light from the femtosecond laser; and a nonlinear medium configured to generate a broadband light by mixing spectral components of the output from the non-linear waveguide. Optionally, at least one dispersion compensation element may be placed between the femtosecond laser and the nonlinear waveguide and/or between the nonlinear waveguide and the nonlinear medium.

Abstract: A tunable laser including: a reflecting mirror; a partially transmitting mirror; a gain medium energized by a pump source; a pair of mirrors surrounding the gain medium, a first prism and a second prism located between the gain medium and the reflecting mirror; the first prism receives radiation from the gain medium and disperses the radiation to the second prism; the second prism receives and directs the radiation towards an optical element which filters the spatially dispersed radiation based on the position to the second prism, the radiation resonates between the reflecting mirror and the partially transmitting mirror; the second prism is placed on a stage moved by a linear motor such that a desired center wavelength is obtained by moving the second prism to a position so as to allow radiation having the desired center wavelength to resonate between the reflecting mirror and the partially transmitting mirror.

Abstract: Disclosed are ideas to produce an add-on device which turns widely used high repetition rate lasers used for 2-photon microscopy into a light source which can be used for 3-photon microscopy. The add-on encompasses a device to reduce the pulse repetition rate of the high repetition rate (>50 MHz) laser source (laser or OPO) to less than 10 MHz which allows for higher pulse energies while maintaining reasonable average powers. If the high repetition sources operate below 1250 nm the add-on shifts or broadens the seed light to cover 1.3 μm to 1.8 μm before amplification. If the high repetition rate source operates at or around 1.3 μm the add-on only needs to amplify the pulse after downshifting the repetition rate. In another implementation the add-on shifts or broadens the 1.3 μm light to cover the spectral range out to 1.8 μm before amplification.
