66 -- FEMTOSECOND TUNABLE SYNCHRONOUSLY PUMPED OPTICAL PARAMETIC OSCILLATOR LASER SOL 52RANB60C040 DUE 071996 POC Marilyn Scherer, 303-497-3657 The National Institute of Standards and Technology intends to purchase one femtosecond tunable synchronously pumped optical parametric oscillator laser system. The specifications are given below. 1. Femtosecond tunable synchronously pumped optical parametric oscillator. a. Temperature controlled lithium triborate crystal for 90 degree phase-matched generation of signal and idler wavelengths from titanium sapphire pump laser in a signal-resonated optical parametric oscillator configuration. b. Repetition frequency: greater than 80 MHz, matched to a commercially available titanium sapphire laser source. c. System must have an automated piezoelectric cavity length adjustment to maintain lock of cavity length frequency as the laser is tuned, less than or equal to 5 um cavity length. d. Signal tuning range: 1.10 - 1.35 um; 1.34 - 1.60 um. e. Required pump source: less than or equal to 2 watts at 775 nm and 810 nm for the wavelength ranges above, respectively, 130 fs, 82 MHz. f. Noise: less than 2% rms, 10 Hz - 1 MHz. g. Spatial mode: TEMoo. h. Beam diameter: less than 2.0 mm at 1/e2 points. i. beam divergence: less than mrad full angle. j. polarization: greater than 100:1. k. Idler wavelength range: 1.65 - .3 um. Microprocessor controlled: Both crystal temperature and cavity length controlled for tuning of wavelength and for wavelength scans. Output pulse duration: less than 130 fs; average power: greater than 150 mwatts. 2. Wavelength extension conversion kit. a. To extend the 1.10 - 1.35 um signal wavelengths to the 1.34 - 1.60 um range. Power specs listed above. 3. Frequency doubler to extend wavelength of parametric oscillator to visible. a. Beta barium borate crystal doubler to achieve 560 - 660 nm; power: greater than 50 mwatts typical. 4. Pump output option. a. To output couple greater than 250 mwatts of titanium sapphire light out.
