Patent number: 11817672Abstract: A pulse stretching fiber oscillator (or laser cavity) may comprise a chirped fiber Bragg grating (CFBG) and an optical circulator arranged such that a first portion of a beam that is transmitted through the CFBG continues to propagate through the laser cavity while a second portion of the beam that is reflected from the CFBG is stretched and chirped by the CFBG and directed out of the laser cavity by the optical circulator. Accordingly, a configuration of the CFBG and the optical circulator in the laser cavity may enable pulse stretching contemporaneous with outcoupling, which may prevent deleterious nonlinear phase from accumulating prior to stretching.Type: GrantFiled: January 24, 2022Date of Patent: November 14, 2023Assignee: Lumentum Operations LLCInventors: Martin H. Muendel, Simonette Pierrot

Patent number: 11417999Abstract: An optical assembly provides dispersion control, modelocking, spectral filtering, and/or the like in a laser cavity. For example, the optical assembly may comprise a diffraction grating pair arranged to temporally and spatially disperse a beam on a forward pass through the optical assembly, a reflective device at an end of the optical assembly, and a focusing optic arranged to create a beam waist at the reflective device. The beam waist created at the reflective device may cause the beam to be inverted on a reverse pass through the optical assembly, and a temporal dispersion and a spatial dispersion of the beam may be doubled on the reverse pass through the optical assembly to form a temporally and spatially dispersed output from the optical assembly.Type: GrantFiled: November 22, 2019Date of Patent: August 16, 2022Assignee: Lumentum Operations LLCInventors: Simonette Pierrot, Martin H.

Patent number: 11029467Abstract: A method may include performing an active alignment to enable optical coupling between a first optical fiber and a second optical fiber via an imaging structure. An end of the first optical fiber may be at a first location on a first surface of the imaging structure. The first location may be a first transverse offset distance from an axis of the imaging structure. An end of the second optical fiber may be at a second location of the first surface of the imaging structure. The second location may be a second transverse offset distance from the axis of the imaging structure. The method may include fusion splicing the end of the first optical fiber at the first location on the first surface of the imaging structure, and fusion splicing the end of the second optical fiber at the second location on the first surface of the imaging structure.Type: GrantFiled: September 30, 2019Date of Patent: June 8, 2021Assignee: Lumentum Operations LLCInventors: Martin H.

Publication number: 20140293404Abstract: An apparatus includes a pulse conditioner and an amplifier. The pulse conditioner configured modifies a temporal intensity profile of an input laser pulse, thereby creating a conditioned laser pulse having conditioned temporal intensity profile with a misfit parameter, M, of less than 0.13, where: M 2 = ? [ ? ? ? 2 - ? ? Pfit ? 2 ] 2 ? ? t ? ? ? ? 4 ? ? t , where |?(t)|2 represents the pulse temporal intensity profile of the conditioned laser pulse and |?Pfit(t)|2 represents a parabolic fit of the conditioned laser pulse. The amplifier increases the power of the conditioned laser pulse creating an amplified laser pulse. In a method a temporal intensity profile of an input laser pulse having a pulse duration of at least 1 ps is modified to create a conditioned laser pulse, which is amplified to create an amplified laser pulse, which is temporally compressed to generate a compressed laser pulse having a compressed pulse duration less than the input pulse duration.Type: ApplicationFiled: March 31, 2014Publication date: October 2, 2014Applicant: EOLITE SYSTEMSInventors: Simonette Pierrot, Francois Salin
