Title: Small solid-state laser
Inventor: TOMARU TATSUYA
IPC: H01S3/0941
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To provide a solid-state laser which can be enhanced in laser pulse repetition frequency when it oscillates pulses and lessened in size. SOLUTION: A cavity is composed of the right side of a gain crystal 1 and the right side of a chirp mirror 2. Exciting light is made to impinge on a small solid-state laser from the chirp mirror 2, and an output light 4 is taken out through the gain crystal 1. By adopting a chirp mirror, parts required for dispersion compensation can be lessened in size. The gain crystal is mirror-coated, so that necessary mirrors are lessened in number, and a laser system is decreased in size as a whole. As a result, a pulse repetition frequency can be enhanced.

Title: Semiconductor integrated circuit
Inventor: OSAGAWA YUJI
IPC: H03M1/66
Filed: 1990-11-28
Abstract: PURPOSE:To change the output synchronously with an event by constituting a D/A converter of plural registers, where digital values are stored, and a resistance ladder which converts output values from these registers to an analog voltage. CONSTITUTION:Transmission gates 1h, 1g, and 1f are opened in this order to write a digital value from a data bus 4 in registers 1e, 1b, and 1a in this order. Since a resistance ladder 2 generates an analog power corresponding to the value of a register 1c, the analog voltage corresponding to the first written digital value is outputted from an external output terminal 3. When an overflow signal 5b from a timer 5 is made effective, transmission gates 1d and 1e are opened, and the second written digital value is stored in the register 1c, and therefore, the analog voltage corresponding to this digital value is outputted from the external output terminal 3. When the overflow signal 5b is made effective again, the voltage corresponding to the third written digital value is outputted.
