The Carmel X-1750 from Calmar Laser is a Femtosecond Fiber Laser that operates at a wavelength of 1750 nm. It provides an average output power of over 1 W and pulse energy of over 12.5 nJ with a pulse width of less than 80 fs and power stability better than 1% RMS. This laser has a spectral width of 50 nm (FWHM) and a repetition rate of 80 Hz. It produces a round beam of a diameter of 1.2 mm with a beam quality M2 better than 1.2. This laser has a warm-up time of 15 minutes and can be controlled via an RS-232 serial port or monitor port interface.
The Carmel X-1750 is based on Calmar’s ultrafast fiber seed laser platform which utilizes the proprietary Mendocino saturable absorber technology to deliver reproducible and reliable mode-locking at turn-on. It is designed for deep tissue imaging and operates in the near infra-red region between 1600 and 1850 nm to enable multiphoton imaging and tissue interactions at exceptional penetration depths. This NIR region offers a unique high transmission window for brain tissue because of reduced scattering and absorption. This laser supports remote system diagnostics and can be configured for dual wavelength output to enable alternating access to 1750 and 1550 nm outputs.
The Carmel X-1750 requires an AC supply of 85-264 V and consumes 200 W of power. It is available in a compact laser head module that measures 9 x 18 x 3.5 cm with a 0.5 SMA connector and air cooling. This laser is ideal for multiphoton microscopy, optical metrology, bioimaging, materials characterization, deep tissue interactions and nonlinear spectroscopy applications.
