TeraDiode is manufacturing the first high brightness direct diode laser for industrial laser sheet metal cutting and welding. TeraDiode's core technology is based on Wavelength Beam Combination (WBC) which was developed at MIT Lincoln Laboratory. Using WBC technology, TeraDiode has demonstrated a 100x brightness enhancement over conventional kW-class direct diode lasers. We are commercializing 2 kW...
Highly linear and price competitive 1550nm GaInAsP DFB RWG lasers with low distortions and low chirps for QAM applications was developed. Their frequency dependent CTB was studied through band gap engineering in the active region.
We used the molecular wafer bonding technique to develop a hybrid widely tunable, monomode III-V/Si laser for wavelength division multiplexing, with a tunability over 35 nm and an output power in excess of 3 mW.
Laser-microcavity relative frequency fluctuations caused by thermal locking are studied. The locking of laser-microcavity detuning causes microcavity temperature fluctuations that transfer pump frequency noise onto the microcavity modes within the thermal locking bandwidth.
A high power monolithic nanosecond pulsed fiber laser at 1064nm in MOPA configuration was reported with more than 300W average power for 475 ns pulses at repetition rate of 100 kHz.
Doped single crystalline fibers (note: not the photonic crystal fiber) are efficient to emit cw and high-brightness broadband light. Various crystal fibers based broadband emissions and lasers centered from blue to near infrared will be discussed.
We demonstrate a three-wavelength Tm3+:ZBLAN fiber laser emitting simultaneously at 1460 nm, 1503 nm, and 1873 nm and its application in single-pass absorption measurements for detecting and quantifying water concentration in acetone.
