| 20080253419 | Diode Pumped Laser - A switching mechanism ( | 10-16-2008 |
| 20090168822 | LASER CONTROL APPARATUS AND ELECTRONIC DEVICE USING THE SAME - A laser control apparatus includes a detector and a switch module. The detector is for detecting states of a mechanism having a closed state in which the mechanism blocks a laser and an opened state in which the mechanism unblocks the laser. The switch module is for transmitting an emitting command to a laser unit to emit the laser. When the opened state is detected, the switch module stops transmitting the emitting command. An electronic device using the laser control apparatus is also disclosed. | 07-02-2009 |
| 20090190621 | Laser Turn-On Accelerator Independent of Bias Control Loop Bandwidth - An accelerator circuit is incorporated in a laser diode system for accelerating the turn-on operation of the laser diode independent of the control loop bandwidth of the laser diode system. The accelerator circuit provides a boost current to a compensation capacitor upon laser turn-on which compensation capacitor operates to establish the control loop bandwidth of the laser diode system. The boost current enables the control loop to increase the bias current to the laser diode quickly. When the laser diode reaches the desired operating point, the boost current is terminated and the control loop of the laser diode system resumes normal control of the bias current. In one embodiment, the accelerator circuit includes a timer circuit controlling a current source to implement open loop turn-on control. In another embodiment, the accelerator circuit includes a comparator circuit working in conjunction with an one-shot logic circuit for providing close loop control. | 07-30-2009 |
| 20090219965 | POWER-SAVING LASER POINTER MOUSE - The present invention provides a power-saving laser pointer mouse including a battery, a micro-controller and a laser diode. The power-saving laser pointer mouse can be operated in multi-stage power-saving modes according to the voltage value of the battery. The lighting time interval of the laser diode is adjusted by the micro-controller according to the voltage value of the battery. When the voltage value of the battery is reduced, the lighting time interval of the laser diode is shortened so as to achieve the power-saving purpose. | 09-03-2009 |

| 20130301665 | LASER LIGHT SOURCE MODULE, LASER APPARATUS AND LIGHTING METHOD THEREFOR - A laser light source module includes a laser source, a connecting unit, a controlled switch unit, and a verification unit. When a verification signal is received, the verification unit judges whether the verification signal complies with a verifying condition. If the verification signal complies with the verifying condition, the controlled switch unit is in the on state, so that a first output voltage is transmitted to the laser source through the controlled switch unit to drive illumination of the laser source. Whereas, if the verification signal does not comply with the verifying condition, the controlled switch unit is in the off state, so that the first output voltage fails to be transmitted to the laser source through the controlled switch unit and the laser source is turned off. | 11-14-2013 |
| 20140334509 | METHOD AND DEVICE FOR PROCESSING MATERIALS USING A PULSED LASER BEAM GENERATED BY A FIBER LASER - A method and a device include a fiber laser generating a laser pulse for processing materials. An optical switching element disposed in a beam path of a laser beam is closed at the earliest when an output power of the laser beam falls below a specified value. | 11-13-2014 |
| 20150085887 | SEPARATELY CONTROLLABLE ARRAY OF RADIATION ELEMENTS - A good way to avoid extreme current levels when supplying large amounts of power is to increase the voltage. The easiest way to do this is connecting the radiation elements (e.g. laser diode pixels) in series (La | 03-26-2015 |
| 20150110143 | ADJUSTABLE IMPEDANCE LASER DRIVER - An assembly that includes a laser diode and a driver circuit that operates to give the assembly an adjustable impedance. The driver circuit adjusts impedance by repeatedly alternating between two operational phases. In one operational phase, current is primarily or fully supplied through the laser diode using a first current path being from the first supply node, to the laser diode, and into the second supply node. In the other operational phase, current is supplied through the laser diode using a recirculating second current path. The current through the laser diode increases during the first operational phase, and decays during the second operational phase. For a given applied voltage level between the first and second supply nodes, the duty cycle of the first and second operational phases may be adjusted so that the current through the laser diode is approximately a target current. | 04-23-2015 |
