Acousto-optic mode lockers (AOML) modulate the loss within a laser cavity at its resonant frequency, effectively “locking” the phase of the longitudinal modes to generate very narrow laser pulses of high intensity. Gooch & Housego’s mode lockers for Nd:YAG, Nd:YLF, Ti:Sapphire and Argon Ion lasers can modulate at up to 200 MHz, yielding near-theoretical mode locked laser pulse widths. Antireflection (AR) coated and Brewster angle options are available. Customized one-off mode lockers can be designed for demanding scientific and OEM applications.

The acousto-optic mode lockers from Gooch & Housego are manufactured using high quality fused silica, polished and fabricated in-house to ensure high quality and reliability. >99% transmission at 1064 nm is achieved by using a durable in-house antireflection V-coat. Low scatter and tight quality controls ensure that every mode locker is capable of handling high peak laser power over the long term without damage. The standard mode lockers include operating frequencies from 38 MHz to 80 MHz. The more modes are locked together in phase, the shorter the pulse. G&H’s standing wave mode lockers can obtain near theoretical mode locked laser pulse widths, with industry-leading transmission performance.

The high-Q mode lockers can be used for Nd:YAG, Nd:YLF, Ti:Sapphire and Argon ion lasers at near infrared wavelengths to achieve picosecond and femtosecond length pulses at repetition rates of up to 200 MHz. The short pulses generated are often used in applications like nonlinear optics, optical data storage, femtosecond micromachining and multiphoton microscopy. High repetition rates are often desired for scientific applications, including those using optical heterodyne detection for spectroscopy, LIDAR or telecommunications.

RF driver selection impacts mode locking system performance. Active temperature control of the acoustic resonator can assist in controlling resonant frequency such that resonance at the precise frequency of the driver's oscillator can be maintained. We can assist choosing the right driver for your application. Contact our sales team to identify the best RF driver for your specific application.

Applications: Femtosecond Micromachining; fs/ps Lasers (Nd:YAG, Nd:YLF, Ti:Sapphire, Argon Ion); LIDAR; Multiphoton Microscopy; Nonlinear Optics; Optical Data Storage; Optical Heterodyne Detection For Spectroscopy; Telecommunications
